What was your relationship like before? You're married so it must have been nice!
Its a bad situation for your both and for him. He's probably not feeling too good having his spouse come over to live in that situation, living with his parents and no job... is he depressed maybe? Indeed, what happened with him? It sounds like he went from being someone you fell in love with (sounds like you like adventure) to someone who's a little depressed for sure. Was he fired? Something happened? Maybe he needs some support?

Moving abroad also is a big thing, you made a big change in your life, so its natural to be disappointed with just an empty drawer. Of course you're broken hearted, this big change was meant to be for the better and now you're at home with someone you barely see who sleeps all day, that's not what you hop the pond for! But, his life is nothing at the moment, it seems, what else would he do? I think if he was busier he'd probably do more, but it sounds like he's pretty down right now. Someone who does nothing... does nothing! But don't judge him. Curiosity not judgement is key! He's different but maybe he's the same person grappling with something negative, bad etc.

Also, if you're not working, are you sat thinking about it all day? That's probably titling you quite off balance, in terms of your situation with him, and your mental health. When you can work, you can get some perspective and it might chill you out. In the meantime go for a walk, or, in the US, a drive, or something. Read a book, do something else. Go see a movie, remember who you are, you came there to live your life right, not just to be with him? Start building up your life there! Go make friends etc. Keep going as planned. He seems to be in a bad place, don't let that destroy everything, it might be temporary. But, if he's depressed, or down, or a bit sad, seeing it affect you will make it worse on him, keep him in bed maybe or whatever. Remember yourself, don't let it turn into resentment, otherwise it'll die.
