conflicted

My SO already has a kid, and he doesn't want another. Nevermind I'm 4 weeks pregnant. He isn't taking into account my wants or needs, or the fact that I am uncomfortable with abortion. I am about to graduate college, so I feel like I can handle the situation, potentially without him. But we have an abortion appointment set up for Tuesday anyways. Since its the abortion pill he says it doesn't count as an abortion. Help!
