If he wants to do what you want, have you tried say to him you want him to bring home his thoughts and that he talk to you about what he wants and go through with it? Have you tried tell him you want him to not work 3 jobs and spend more time home?

Maybe if saying this he may do it?

Its hard to know whether he is just the quiet man or if he has an issue expressing himself. Maybe you can ask him what he thinks and feel about that? I dont know if you have asked him, I assume you have, but that he doesnt answer anything else than what you say. If so is then I must say it sounds very weird to me too, actually. I would assume he must have some opinions about something.

Hopefully someone here will have a good answer to you.
