There has been a lot here about the rights as a father not to have the baby if he doesn't want it. I agree that ideally it should be a joint decision that both can be happy with, but at the end of the day, he chose to have sex, no contraception can be viewed as 100% safe. By choosing to have sex, he has to take into account that there may be a baby created and take responsibility for that decision. i am presuming that both parties did not agree in advance that any pregnancy would be terminated and that you are not going against that decision (which you are able to do, but to ask him to maintain the child would be more of an issue).
i get the feeling from your responses that you want to keep the baby but feel for various reasons that you shouldn't.
Anyway, I hope that you feel that you can make the right decision for you that you can live with in the future. We are talking about a future human being here who deserves to be loved and wanted - preferrably by both his/her parents. None of us know what the future holds, but for me, money, etc is all a secondary issue to the love that is needed.
