I didn’t mean to hurt your feelings or make you feel like I don’t care. You are an amazing person and such an important part of my life. I feel so devastated for forgetting your big day. I don’t know how it could have slipped my mind.
Please know that I am unbelievably sorry for missing your birthday. I’m so sorry I wasn’t there for you, and I hope you can find it in your heart to forgive me. If I have to beg for your forgiveness, I will.
I hope you had a birthday as incredible as you are.
I want you to know that I'm very sorry for my tardiness in wishing you a happy birthday.
I may have forgotten your special day, but I remember all of those days we spent together that were so special to me. I hope you can forgive me and focus on all of those special days, too
I’m sending your birthday wishes later than planned this year as your birthday came around much quicker than I was expecting, my friend! It really crept up on me!
