How can men be so heartless

Ever since I got an abortion, he wanted me to have one but I wasn’t sure about it, but after I got the abortion I’ve just been so hurt and sad and I have nightmares every single night and I would tell him how much this is effecting me and he brushes it off like it’s not a big deal and makes me feel even worse. I had to do everything all alone too. So I told him I needed some space and time, I just can’t do this anymore with him. I love him but he just has no sympathy for what I’m going through and he wanted this abortion and I went through with it because I couldn’t do it alone, but sometimes I feel like I should of kept it.

I just don’t know how to go about with our relationship... he’s so self centered and doesn’t care about what’s going on with me. I don’t deserve this..
