Boyfriend not wanting our baby........

I have been dealing with this older guy for little over a year now. He has expressed to me that he don't want any more children, and I have told him that I want at least one, whether it's with him or not.......now I'm pregnant he wants me to get an abortion and I'm not doing that.......so what shall I do? I was thinking bout making him sign his rights over. Oh yeah we live together and not speaking to each other. Any opinions on what I should do laides?
