I'm sorry for what you're going through, it sounds horribly depressing and disappointing. Why isn't your husband working?

I would say put down your foot with him and give him the business. You up and moved for him, and he's not doing anything to help you two financially. I assume you wish to move out of his parents home and live independently together on your own. Why isn't he working towards that? I would give him an ultimatum and tell him that things MUST change or else you will consider leaving.
