You know, ... yeah.... it's extremely frustrating to watch. He tells hubby how things are but doesn't do anything about it. We've suggested therapy, reading self-help books, telling him things from our own experience but he stays stuck. Only thing hubby and I have come up with is to just listen and not try to "DO" anything. It just frustrates us more. The time will come when he's had enough, that life can be better and he'll find the strength and courage to stand up for himself.
I used to be married to a man very much like his wife. It took me 12 yrs "to see the light."
My reason for posing this question, in reality, was to find info for hubby that he could present to this man and maybe hurry him on his way to recovery. Don't think it's gonna happen just yet.

It just gets so old listening and watching and no action! Ah, well...
