What do I do?

I got pregnant with my son my sons dad wants nothing to do with us. He always joked about knocking me up. When I finally got pregnant ( he said he didn’t finish in me, when I took plan b just in case he came in me AGAIN). HE “can’t” pull out for some reason. He says I am trying to trap him and he doesn’t want a baby with me, he wants me to get an abortion leave his family out of it and not ask him for anything & stay out his life. Is child support worth it? Who has been in this situation? I don’t want anything to do with him. He hasn’t helped with anything either. Maybe it’s my fault cuz he TOLD me to get an abortion? And I didn’t so I deserve to raise him on my own.
