Boyfriend doesn't want the baby

I am 19 and my bf is 20 about to turn21. He told me he doesn't want the baby and is treating me like I'm the problem. He said he wants me to have a abortion but I don't believe in that and says he's not ready. I wasn't planning on getting pregnant but now I have to take responsibility for my actions and i feel that he should too. Please please please can someone help me out here?
