What do I do Im pregnant and the babys dad being a jerk?

Everything was fine until I found out I was pregnant and hes been a complete ever since. I was staying with him at his house and now he wont even talk to me or let me be over there if I go over there he either leaves or flips out. I have no idea why he is acting like this but he is being completely immature and dumb. I dont think I should have to be treated like this especially when Im pregnant with his kid He is a complete hole I want to talk to him about what IM going to do but he is being so stupid. This came out of nowhere like I said everything was fine before I dont know how someone can act like a complete over something like this it completely boggles my mind. He wants me to get an abortion and I just dont know what to do. He will not talk to me at all if I try to call him he wont answer and like I said I cant get a hold of him. He said he would pay for an abortion which again boggles my mind as to why he wont even talk to me it makes no sense If I knew he was gonna act like this I would have never let this happen. I dont really want to have an abortion but I dont want to have a kid with someone who is treating me like this now and I would have to put up with this for the rest of my life. This is not how it's supposed to be. It would at least be easier if I thought we going to be together and then it didnt work out later but I have to know this now it makes it so much harder. Im 7 weeks pregnant.
