That is one of the cruelest things I think a ex boyfriend could do to his hurting ex. I wanted to cry when I read that part about him mocking your pain. Even if he's not your boyfriend anymore, I think he should be a lot more nicer because you are ill. I mean, I'm not saying he has to call you all the time and stuff. But I would think he would care enough to know if you were ok.
Hateful!
I'm sorry. I hope you get well. And get over him.
