True Confession: I was a virgin, but he kept pressuring me & now I’m pregnant

I have been seeing somebody for 9 months now. We were together for 8 months when we had sex. I was a virgin, and believed in sex after marriage until he came in and changed it.
He was very pushy for sex throughout our relationship, and I decided to hold it back. So, we had a break-up on the 18th of March because I wouldn’t be a real girlfriend by sleeping with him, I guess, and that he was sexually frustrated. So, I told him, “it’s okay if you don’t want to be with me. I’ll let you go and I’ll move on.” I didn’t want to beg him like always to, “come back and I love him, etc.”
He was fed up with being needy. He texts me later on saying, “meet me tomorrow, we’ll talk this through.” And, I say “No, I have school tomorrow.” And, he says “last chance.” So, I got a little worried and I went to see him. So, we get to his house and he takes me into his bedroom. He starts taking my clothes off and he says, “I just want to lay down with you naked,” and I thought, “Oh, okay, at least he doesn’t want to screw me.” Then, it kind of went a bit sexual. He puts on a condom and does the deed. And, I lay there hoping that he’ll change from that day onwards, and that he’ll see that I love him.

Guess not. Two weeks later I realize I’m pregnant. My blood test confirms this. I let him know of this – at first he seemed okay – we were discussing what we were going to do. And, then a couple of weeks later he’s picking fights with me over stupid things, being cold, and being distant.
I’m all alone and don’t know what to do. There are days where he disappears and doesn’t talk to me and I’m left feeling miserable and used. Any advice would be great.
