Don't know what to do about husband.

I am glad that he has a job that he enjoys, but it doesn't lay shit and mine is even worse. He makes about $15 an hour (full time department manager) and I make $8 (part time gist shop clerk). I can't afford to go to college right now and I'm trying to get a better job, been trying for a while now, no luck. I want to better myself, but idk what I want to do for a living and need to find a way to pay for college (gonna try for a grant). My husband has his associates degree, but he has no desire to try and get a better job. He wants to stay where he is and that just won't support us especially if we get pregnant. I just don't know what to do. I don't want to be the main supporter of the family because I want to actually be able to be a mom.
