Yeah @PerilousPoozer I think the best thing you can do for him is encourage him to talk to them. Offer to go to counseling with him and practice, offer to act as his family so he can practice what he wants to say, offer to be with him when he talks to them. Or - offer to be his family, now, and let them fade into the night. They are causing more pain than any joy they bring. Help him set expectations and make them clear, that's all you can do with shitty people.
