> He has a job now, so when he has work, I'm by myself, and get super lonely.
This is one of the tragedies of modern life.
Women like successful men. Men like being successful too. And everyone needs money to avoid being on the street. Unfortunately, successful men are too busy being successful to have much (or any) time left for their partner. Likewise for successful women.
There's no good solution. Chances are when he gets home he just wants to sleep, but that doesn't change your feelings. I think your feelings may be justified, but what can he do short of cloning himself or learning to go without sleep, which is unhealthy and will probably get him fired due to subsequent lack of productivity.
The only thing I can suggest: get a full-time job yourself. Then you'll both be exhausted so neither will complain. :(
