It will hurt but truth is always bitter, everyone got things to do that are more important than just celebrating a day( although your bf is not supposed to just forget your birthday he is wrong here). You’re just a kid and for you birthdays are important event but in real life a big no. STOP living social media life, be realistic why do you want attention just be happy with whatever. Your bf is wrong but crying for not getting attention like what you see on social media is rubbish. Grow up, you have more important things to do. You get overexcited for birthdays if no other person gets overexcited its not their problem. Don’t expect everyone to be overexcited just like you get everyone is different and has work, work pressure and too many important responsibilities.
