He won't leave...

Did any of you girls have this problem? Today I told my boyfriend I'm pregnant and he told me he wants me to get an abortion but I said no. Now he's telling me I'm ruining his life so I told him go ahead leave and he said no I can't do that, but is still trying to munipulate me to get and abortion. I just don't understand it. And I don't know what to say to him anymore.
