His priorities..I don't know what to do

I am Currently 19+3 weeks pregnant and I am living with my boyfriends parents at the time. We are both still in school and actually graduating at the same time in one month. he is becoming a EMT and I am going to be a NA. We always talked about moving when we start working but I got pregnant and I don't think it's a good idea for me to start working until after I have the baby. I still want to get out of this house with his parents. He will start working in September and that gives us a little time to save to get our on place before the baby but he doesn't want to do that, He wants to get a car meanwhile he already has a truck... it just pisses me off that he would rather stay cooped up in his parents house with the baby rather then have our own place. I just don't know how to get him to change his mind. We could just rent for now until I start working ... plz someone give me advice
