There are laws against abaondining a spouse, there is a bailiff that can force him to pay you support. I don't think he can legally throw you out of the house either.
He will bluff you if he can.
You should be able to get some legal advice for 1 hour free from a few laywers.. I would talk to about half a dozen to find out your options...
I would continue reporting to the military though...
I would be wary of accepting any $$ from him or signing anything. He will be setting a presedent there.. for example if he gives you 200 bucks and then another 200 in tewo months then he can tell the court that you have accepted 100 bucks a month support...
Art of War is a great start to get in the right mindset no doubt.
