19.. Boyfriend is 24.. Doesn't want baby...

Somewhat of a long story... Need some advice.. 
My boyfriend and I have been sleeping with one another constantly without any protection and he refuses to wear a condom and he recently brought up to me that he wants a baby so now we are here at 5 weeks pregnant and he changed his mind and says that he will leave me if I keep the baby.. I have had 2 abortions and one miscarriage and I don't want to keep using abortion as a contraceptive.. I am leaning towards keeping the baby... Every time I bring it up he freaks out and gets mad.. We both have stable jobs and we can kind of afford to keep the baby.. But he just doesn't want it.. I'm scared to be a single mom because my mom is a single mom and I really wanted my child to grow up in a home with two parents because I never got that.. I'm so confused and it breaks my heart.. I don't know what to do..
