Lots of good advice above. It's really stressful when people you care about go through bad stuff, or in his case, act like complete assholes. About all you can do in this situation is listen, be a friend, offer suggestions where they are welcome and also give advice based on what your values are. You don't really have any control over what goes on, but you're there for them and that's what matters. Hope for the best, and try to help where you can, if you can. That's all anyone can do.
