I agree with Perna. You seem to be way to concerned about him and his career so he can support you. Even if you cannot get a job in your trained field there are others (part time is better than no income) plus disability if functioning is too difficult because of external issues.

It sounds like he is depressed and needs some freedom. Maybe he is too young and not ready to really settle down. I think you two need to have a talk about future goals and plans. I also think you need to find out if he really wants to make it work. I am almost 23, and have been in a long term relationship and compromise is not always easy. I am creating ways to reach my dreams while supporting my bf and baby (cat lol). It effing sucks because I feel tied down sometimes. Hes at that age too and you have to remember he is still growing up into his adult identity. College does not prepare you for the real world when you have parents who support you.
