What should you do or say if your boyfriend forgets your birthday?

It's really hard for that to happen. Explain to him simply that he forgot your birthda and how you felt: angry, frustrated, unthought of, etc. But it won't do any good to stomp your feet and throw a tantrum unless he doesn't care. I promise you no guy is worth your time if he forgets AND does not care that he forgot! If he is sorry and he seems to mean it then forgive him and next birthday drop a hint a weel earlier about your birthday or make a joke "Remember last year how you forgot my bday?" *laugh* or "If you forgot my bday this year you aren't going to have a ball sack."....Okay you don't have to go that far lol but good luck and let him know how you feel. ;-)

My boyfriend forgot my birthday till today and one of his friends said to me is it your birthday today and i said no not till the 23ed and he was all like yea i knew that i said yea sure that's why you got him to ask for you right hahah then we laughed for a bit it was funny but i think that he wont forget next time.
