21st Birthday Romantic Love Letter to Him

• On your 21st birthday, I wish you all the cute best things in life, and I am very thankful that you were born and given to me. You mean the world to me! On this particular day of your birth, I promise my love for you will only get stronger with time. My care for you knows no boundaries and it can never fade away. Happy birthday my dear and first love, from the bottom of my heart.

 

• As your big day arrives, I wish you a pleased birthday! I know it’s not easy being 21. One of the world’s most famous persons was 21 when they turned. And that person was my friend John! He is such an awesome guy. I think you will enjoy life when you meet him. So, try not to be nervous tomorrow and just be yourself. If it doesn’t work out between you, that’s fine because he loves me too!

 

• You’re turning 21! This is a considerable anniversary that signifies a new chapter in your life. I have been with you through good and bad times, happy and sad, but I am always here for you. You are my friend forever. I know that you want to have fun on this special day. I hope this day will not just be about the vodka, but the happiness of your best friends and the lucky girl who will get to share the party with you.

 

• I cannot believe you are 21 today! You have made us so proud and happy. We will always be there for you no matter the circumstances. From the moment we first saw your beautiful face, we felt lucky to have you in our lives and we were right, with your contagious smile, how could anyone resist you? We love you and wish you all the best in your new age!

 

• Hi there handsome! To say that I love you seems very cliché, but I cannot find other words to express my feelings. Since we met, you have been my inspiration and motivation, and I want to spend all my life with you. Happy birthday, my sunshine!

 

• Dear love, I just want to thank you for all you have done in my life. Before I met you, my life was nothing more than a succession of meaningless events. There was no occasion to celebrate anything. Now, we are planning to spend the rest of our lives together. You have made me believe in true love and all its glory! Happy birthday!

 

• I am proud to be your friend and happy to call you mine. You have always been there for me no matter the time I called or how much trouble I was in. Thank you for your unconditional support and all the wise words you keep handing down to me.

 

• Hi love. It is your 21st birthday and today I’m sharing my birthday love letter to show my appreciation to you. I hope you will have the best time with your family, friends and loved ones. Stay happy always my dear. I love you.

 

• I am sending you this letter to the most handsome man on earth to mark your 21st birthday. I miss your beautiful smile, your sense of humour and the way you talk. I am proud to call you mine, as you are everything I have ever looked for in a guy. You are my dream come true, my life, my love. Happy birthday!

 

• Darling, I am writing to you on your twenty-first birthday, wishing you a life full of joy and happiness. Happiness is what a person has inside and you should be happy every minute for being born in this fantastic world. I hope this day will be memorable in many ways for you as it is my first birthday gift to you from heaven: waking up each morning!

 

• I think of you, yet every time I’m disappointed. Why do I love someone who never seems to notice my existence, or acknowledge the love that I feel for him? All I want to say is my dear boy (or boyfriend), for this birthday and all the upcoming birthdays, I wish you all the best and lots of life fulfilment.

 

• Every day I wake up and thank God for making my life a success. I want to make you feel special on your birthday, as you have done for me every day in the past twenty-one years.

 

• Dearest, you are growing up so fast! You are leaving your childhood behind and becoming a man. That should make me feel good, but instead, it makes me feel a little lost. This year, I want to surprise you with something extraordinary, just because I love you and want the best for you.

 

• My love for you is like a storybook, I desire us to be together as one and our future to be that happy-ever-after. You have been by my side through all the rough times and I just want to be with you. We have shared so many romantic moments in the past but I dearly wish we share many more in the coming years. Let’s promise each other we will not lose faith in our pipe dreams, let us keep building castles in the air. Happy 21st birthday.

 

• Dearest, it has been more than a month since our last time saw each other in person. I miss you more with every passing day. I think of you day and night, wondering how things are going at your end and hoping everything is going fine. I feel lonely without you around me, my dear husband. And I think it unfortunate just thinking about not seeing you or spending time with you for even a few hours.

 

• Hey handsome! It is my pleasure to celebrate your 21st birthday with you. Today will be the beginning of many great things we both have to achieve in this lifetime. I’m so fortunate to have you in my life, and now I am blessed with a friend like you who always sees the best in me as no one else can.

 

• Your 21st birthday falls on the top of my list of memories that I will always cherish. It was the special day when my father brought us together and told me that you were my prince charming. You have proven infinite love for me in all this time and always encouraged me in my endeavours with your solid support. I cannot thank you enough for all the joys and happiness you have given to me over the years. I wish a happy birthday to the man who made my life worth living.

 

• My love, on this particular day that you are 21, I wish you all the best life can offer. I know, it has been our dream since we were children to grow old together and spend the rest of our lives in each other’s arms. I wish to make the dream come true with all my heart. I know it is impossible without you and your support. In 30 years from now, we will be celebrating your 40th birthday with our grandchildren.

 

• Dear boyfriend, I remember everything you have been to me today. I have always known that you were different, my love for you has grown. My dream is to spend the rest of my life with you. Please forgive me for all the things that made you angry. Count your blessings and be grateful for everything you have. I pray for our love to last forever to never lose one another. Love you, Babe!

 

• Happy birthday to the love of my life. Today is a beautiful day that every memorable and dear to me. As I celebrate another year with you, I want to thank you for all the fun, laughter and joy (every single day).

 

• You are the most fantastic person I have ever met. You have been my strength and rock and a better man than I could imagine. I hope you to be happy always, as you make me so. Enjoy your day, my dear!

 

• As I grow older, I realize the importance of love. It is priceless, the most extraordinary gift nature can offer. You are the one person who knows how to hold my hand in difficult times and wipe away my tears with your tender lips when I am sad. You have brought so much light into my life; I will never be able to return the favour.

 

• Forever and forever, my heart will be with you, as will be your love. Thank you for making every dream of mine come true. Thank you for never judging me, even when I was too hard to handle. Thank you for always being there for me when I needed someone to lean on. Thank you for being the ray of sunshine on my gloomiest days. I love you, dear!

 

• No matter how far, how long it’s been. You’ll always be the best brother in the world to me. We’ve got a long road ahead of us, but as long as we continue beside each other. I know that everything will end up alright. I love you dearly and I wish you all the best on your special day!

 

• Your journey made you one of a kind. The world was never enough to contain a man as great as you.

 

• I can’t even begin to tell you how much I have cherished every moment with you. You have been the one man I look forward to seeing each day. When we are together, time seems to stand still, and we live in a world of our own. I don’t know how else to say it, other than the angel you were sent to me from above. Happy 21st birthday!

 

• Baby, you are intelligent, clever and handsome. You have always had the unique ability to make me smile. You keep telling me that I am the one you want to spend the rest of your life with. We have shared so many happy memories and experiences. As a partner and companion, there is no one better than you in the world. I Love You! Happy Birthday, Darling!

 

• Hi sweetie, I wish you all the best for a long, healthy and happy life. Thanks for being there for me all my life. You are the best thing that has ever happened to me. I love you and will always be true to you. Happy birthday, darling!

 

• ​I hoped and prayed you would be great the day you were born. As you grew older, it became clear that each passing year made you a better person. I am so proud to see how far you have developed. Today is your birthday, a special day when kids celebrate how they came into the world. This day is also your 21st can’t be a coincidence. It means someone has been looking out for you, turning down doors and granting wishes.

 

• Even though we have been apart for a while, my love for you hasn’t faded one bit. We have always been strong and independent, so what is there to fear or lament? You are the reason why I smile every day, without you in my life, I can’t imagine how empty it would be. It is a big deal to feel so connected with someone’s soul. Happy birthday, because I am your love that will never die today and always!

 

• Happy birthday! I hope you have a wonderful day, filled with happiness, laughter and great memories. You will always be special in my heart, and I want you to remember that my love for you is eternal no matter what happens.

 

• This is my chance to tell you how much you mean to me. You’re exceptional and I want to remember this day for the rest of my life and beyond. You’ve been a great friend and companion, not only today but in all the time we’ve spent together. Happy birthday to my best friend!

 

• Before you, I never knew what love is. For me, it was all just fairy tales, but now, I know that I am in love. You are everything to me. There is nobody who knows me better than you do. You have seen me at my worst and yet have always been by my side. I am amazed by your love and care. My heart beats for you alone, and as clichéd as it may sound, I can’t imagine a life without you in it.

 

• You will always remain, my favourite person, with whom I share an incredible bond. Our lives have been held since we were born, but at least our hearts are safe from all the evil surrounding us.

 

• Love is a compelling word, and it can rarely be used to describe my feelings for you. There are dictionaries for writers to look up a word, but it seems almost impossible to tell how you make me feel in words. I think that my love for you can only be understood when you are with me. You make every day worth living and make my emotions lose all sense of direction.

 

• You deserve only my love and nothing else! You have given me a lot in these years we have been together. In this 21st birthday letter, I want to thank you for loving me and being my strength. This day is all about you! I am glad to be with you even though we have been through hard times. My love for you will never change; I just want to make you happy and share your joy in every way possible.

 

• My love and best wishes go out to the most fantastic guy in the world. May you never lose sight of who you are, where you came from, and where you’re headed! Although there will be days when life feels hard, remember that you have someone looking after your heart. Happy 21st birthday my sweetheart!

 

• Happy 21st birthday my prince! I am so grateful for all the little and big things you have done for me! You are the perfect package as a friend, lover, and now a husband. You care for me in the best way possible, and I can’t imagine anything better than that. From the first time we met, I knew you were special. Thank you, my prince, charming.

 

• My sweetheart, I wish you a happy birthday! Thanks for being in my life. I appreciate your warm smile, your unconditional love and all the joy and laughter you fill my heart with every day. You are the best thing that has ever happened to me. This is just a sweet little note to show you how much I love you. I will always think of you like the most fantastic person in my life. God bless you always!

 

• Good day my love, even though you are away, I can’t imagine any other day than today. I miss you, and you know what? I will be flying to you as soon as possible. Until then, I send an email to wish you a merry birthday. Keep up the excellent work and success shall be yours.

 

• My heart is loving and warm today, a day that I celebrate your sweet presence in my life. You have been to me a steadfast companion, a compassionate and understanding man. To think we met for the first time in high school, a time when we thought we knew everything about love that existed in the cosmos. Just imagine the day when I decided to be with you forever before it was too late.

 

• Dearest, I am so glad to be part of your journey thus far. You have been a tremendous source of inspiration for me and never let me down. I wish you nothing but the best for the rest of your life. You are an excellent and courageous person who just can’t be replaced. Love you!

 

• You are the man of my dreams. You are everything I have always wished for since I can remember. I will be with you forever, in this life and the next. You have made me a better person and I am grateful to you. Love you so much! I wish you a happy birthday!

 

    Happy 21st Birthday Romantic Love Letter to Him

• Happy birthday, I hope you have the day you are having your desire. The most remarkable thing in my life is that I celebrate the days like this with someone who has changed my life. He is one of my favourite people in the entire universe. When I met him, I realized that there is someone genuine after all. This day means a lot to me because it reminds me of how our love story has been written.

 

• As you turn a year older, I look forward to seeing your life unfold and become awesome! You seem like the perfect guy to anyone involved in a long-term relationship with you.

 

•  Happy Birthday! And while 21 isn’t one of my favourite ages to live through, it comes with all the promises of new beginnings. But I think what I like best about 21 is your decision to remain single and wait for me to finish college before you commit to me—and everything that comes with it.

 

• My prince charming, turning 21- simply a legend turned reality. What’s even more remarkable is the fact that I am the one to share it with you. My dearest love, I want to tell you how much you mean to me. A simple ‘happy birthday’ is not enough for the angel who has brought so much joy into my life. Each day with you is just as beautiful as this gift of life itself.

 

• One day is not enough to show how much you mean to me, but then again, it is not too much for people like you. You are a great friend who has helped me make my dreams a reality. I wish you the best in life! Happy birthday, sweetheart!

 

• I wish on your birthday to have you forever be able to lead your life in happiness, satisfaction, and prosperity. I want you to know that I love you very much and will remain by your side for the rest of my life. It is with great honour that I make you this promise.

 

• Wow, I hope twenty-one is just the beginning of your journey into adulthood. It has been nice knowing you, John, and I know you will be a great man in the years to come. Here’s wishing you a happy birthday and many more ahead!

 

• I wanted to thank you for always being there by my side. Without your loyal friendship and love, I don’t know where I would be. I can’t remember a world before we came into each other’s lives. You are the best thing that has ever happened to me, and I hope you feel the same way about me. Happy birthday!

 

• My dear husband, you are a man of few words and that has served you well. But I wish I could exchange silent glances with you forever. You are my knight in shining Armor, my rock, my heart and soul. Words may seem clumsy and not befitting you but I bless the Lord that our paths crossed and found each other. I love you always because one day you will give me a baby boy who will be as dashing as his daddy, a tremendous man.

 

• Hey, I just wanted to wish you a pleased birthday. I hope this day will bring many good things into your life!

 

• As a busy, hectic and tedious city life is taking its toll on you, I hope you still find time to give me at least one call. A smile, a joke, a few laughs. Just being with you is enough. But if you need me, know that I’m right here wherever you are in the world. I will venture far and wide as far as it takes just to be with you.

 

• Today as you turn another year older, I want to remind you how much you mean to me, and how blessed I was to have an awesome brother.

 

• This birthday is not just the flower of youth blooming, but the flowers of romance. This is a beautiful day indeed, and I hope you liked this romantic love letter to you.

 

• Dear!! Today, I wish you a happy 21st Birthday! I was thinking about all the times we’ve spent together. We have had our ups and downs, but never lost hope. I’m grateful for your love and support through all these years. Thanks for being there for me whenever I needed you. Because of that, I believe all things are possible.

 

• Today is your memorable day where you are given the gift of life, and I have chosen to make your day extra special. I wish you a life filled with love, laughter, success, and meaningful relationships. I pray for the peace of mind and protection from evil intentions. Lastly, I wish you all things fabulous in life as you celebrate your 21st birthday!

 

• All your life up to this day, I’ve been there for you. Even when no one else was. If a problem arose, I was the shoulder you cried on. Now that you are 21, how about showing me how appreciative you are? Just kidding! I know you will always appreciate me. Happy Birthday!

 

• As I write this letter, I feel like letting the words flow from my heart to your heart. To say I love you doesn’t seem like enough. But I am sure you know that it means the world to me. I say these words every day, and never get tired of saying them again and again. Happy birthday my man! Stay as sweet as you are now.

 

• Your birthday marks the beginning of a new year. Each year I pray that you continue to love me unconditionally and forever. I need you to be around me as you are my support system. You are kind-hearted and a good soul, these are qualities that I need to live. Through you, I have learnt the importance of faith and believe in the divinity of all that is graceful on earth.

 

• Dear, today is the day when people celebrate numbers. When I think of you, the first number that comes to my mind is 25 because October 21st is our 2nd Anniversary! I thought to write this letter because I wanted to tell you how much I love you and how happy I am every time we are together.

 

• I have known you for a long time. You are the best thing that happened to me in life. I cherish you, and I value everything about you: your gentle hugs, your funny jokes and even your cute minor mistakes. Every text message from you makes me 100x happier. My wish is to be with you always so that we can live our lives as one and make each other smile every day in the years ahead.

 

• My ultimate fantasy has always been to marry my best friend. You are all that I need, and you are the one I count on when I need guidance, support and inspiration. We’ve been through thick and thin, and I know you’ll be by my side for the rest of my life. Happy birthday, darling!

 

• I’ll always be beside you and do everything it takes to make your life easy. I want you to know that I love you for the particular person you are.

 

• 21st birthday is a time when you start appreciating the child in you. It is also the day where all your wishes come true and your dreams are set in reality. It’s a day of self-realization and maturity. My million thanks to God for making this day and my best friend Harry came out of it. I love you forever and a day! Happy Birthday!

 

• You are the one that made my 21st birthday an excellent memory. That party was the best I ever had, and I was thrilled to meet some of the people you talked about. You have been so special in my life and have always been there for me. Once again, thank you for all your love and here is wishing you a pleased birthday!

 

• As you turn 21, I want you to believe that I know what it is to be 21. I have been through the ups and downs, and that’s why I will always be there for you. You are a great person, loveable with an attractive kind of smile. Even in your worst time, I have never lost faith in you. Happy birthday, dear.

 

• To my sweetheart and boyfriend, happy birthday, darling. You are a great inspiration to me, every day I learn from you how to be my best self. And I thank God for blessing this world with a tremendous person like you. Please always remember that you are loved forever, today and till the end of time. I love you always.

 

• I prayed for many things, but never for a husband. My prayer was answered in the name of you. Our love did not begin with flowers and chocolates. It started when you stepped into my life and carried me through the darkest times. You are the highlight of my life and I would never leave you to face the world alone. This birthday, I send you all my love, always and forever! You cannot measure the extent of my gratitude towards you.

 

• I have never been able to express my gratitude and love for you. You have always been by my side and loved me as though I am the best thing that ever happened to you. It is your smile that always brightens up my day. For years together, I have shared your laughter, tears and secrets. We have always been together through the good and bad times.

 

• I would like to wish you good health on this special day to my one and only. I love how much you have grown over the years, both personally and as a friend. And I love that no matter how much time passes, your love for me is still the same!

 

• My dear, sweetie! I am so sorry for the time we have been apart. And today, when I realized that this day comes only once every year, I felt like I have lost the most precious in my life. I am aware that many things do not go according to our plan. But please believe me when I say I wasn’t ready to face life without you!

 

• Hoping that a bigger, better, brighter, and funnier year rolls into your sweetheart. I miss you dearly and long to see your smile. Have a fun day my darling!

 

• My dear, closest and most favourite friend, long time no see. Your beautiful and charming face has been always the haunting memory of my dreams. I missed you so much in these many days. The very thought of you makes me feel incomplete and lost. Perhaps, you might not know this but I love you a lot.

 

• My dear, today holds great importance in both of our lives. Now that you have become A Man and I have become A Woman; we have officially entered into the next stage of life. This newfound freedom may seem scary; however, I’m going to be there every step of the way to support you during every one of your endeavours. I promise to stick by you through thick and thin!

 

• I think I have just woken up from a strange dream because I no longer see you in my room. You see, since I was young, your mom used to read us poems about brotherhood love and now only one thing is left in the world that can make me feel that brotherly love – I need you to be by my side because there is nothing in this world that can make me feel warm like a loving brother.
