Insecurity and depression

My “boyfriend” is not good for my mental health...every time I’m down he makes it worse in any way he can. He was in a mental hospital not too long ago and I tried to the best of my ability to make sure he was taken care of when he came home and made sure I called him every single day. I try not to say anything when I get down because he already said himself that he has other things to deal with....which is flaw to me being that I went through with a second abortion for him while he was in the hospital. I’m just having a hard time and I can’t take him treating me badly. I need someone to talk to...
