Help?

So I’m pregnant for the third time and unmarried the first pregnancy was eight years ago and my last two pregnancy is with my boyfriend. Second one ended in a miscarriage and this last one has been going pretty great except Im having a hard time with the being pregnant part I want to be pregnant but then I don’t. Im not happy about it. We at first wanted one but now not so much. Ever since I’ve gotten pregnant my bf has been very distant and just a plan ass towards me. I don’t agree with abortions but I don’t know if I can handle him and his behavior anymore. Money wise I can’t afford to be a single mom of two. Any advice?
