Ex ignoring me because of pregnancy. What should I do?

We broke up a week before I found out that I was pregnant. I had stopped taking my Bc a few months prior so he was more angry about that. He say the worst things to me verbally abusive all of a sudden and he talks down to me alot and countinues to say leave him alone. Its hard to not be desperate in a situation like this. Ive decided to stop contacting him because it makes him angrier. He only talks about an abortion and sending me money for it. He just makes me feel so low. Ive never seen him like this and we were together for a year. I'm 19 and he is a college graduate just joined the miltary and hes in his late 20's. He has no other children or baggage and he seemed so perfect when we were together. No I am afraid of him I feel as though he is under stress from this and military training but what he says things like he will never consider being with me again or in our childs life. Should I leave him alone and let him come to me? Or will he even come back at least to be a father to our child? He says he hates me and I ruined his life because I lied about my Bc to trap him. But we were so happy he would always say he wanted thousands of kids with me. I know not now but we were so in love I ddnt thk it wud matter?
