Baby momma drama.

My boyfriend's baby momma is constantly trying to start stuff between him and I. It doesn't work, but today she said something that really bothered me. She said that he said I was a dope head, and that was why I lost my son or something like that a few years ago.. he denies ever saying it, and I believe him. The fact that she would even think it's okay to bring that up to start an argument bothers me so much. I'm an emotional wreck right now.. she's so much to deal with, I dont know if I can do it... 😭😭😭😭
