It's been 4 months after I broke up with a mama's boy and that I was able to move on to something else, but a painful memory comes from my head: that of my birthday, which we argued about a day before and he thought I was taking advantage of him because it was my birthday (I wanted to go shopping with him as it had been a long time since we went out but he was not able to make an effort so I left with a friend and there was a argument because we had to meet somewhere after shopping but I didn't want to see it). Finally he took the opportunity to tell everyone (friends, his darling mom) to say that I treated him like a dog (I offered him lots of gifts, I was there when he couldn't bear his mother and still the list is long ...) and he did not want to wish me happy birthday and he found an excuse not to offer me my gift (the excuse: your gift is at my mother's) In short, just a painful memory that affected me so far and I would like to share. Any advice ?

(I'm frustrated because it was my first relationship with a guy but...meh he's a mama's boy not a real man)
