How do I decide if I should keep my baby?

I just found out I am 6 weeks pregnant. My live-in boyfriend of 2 years says that it is ultimately my decision but "if he were me, he wouldn't have it". I have two appointments set up for this week, one of which is a consultation at an abortion clinic. I want this baby, but don't want to lose him, and don't want to end up on my own. I have no insurance. What is the best way to determine the right thing to do?
