First, I don't believe there is anything YOU can do for his depression, except for support him through it. He tells you he won't do this and he won't do that. Ask him what he WILL do. In order for you to remain by his side at this time, he has to show you some positives.
You seem to be doing great, although you seem somewhat resentful of being held back by H at this time. This, too, may pass. I suggest you get a good MC and tell him that is part of the bargain, non negotiable. I know if and when my H ever finds his way home, that is going to be an indisputable boundary for me.
