I question whether the C has a clue about how to deal with this issue. The other possibility is that you H is so "good" at selling his crap that the C bought it, the way you did for years. Of course the C doesn't get to live with it.

I know, I'm a broken record. But if you get out, and get some space, it will give your mind a chance to clear. I think the longer you stay there, the greater the chance that he pulls you back in. And then it will only be a matter of time before you are back to the same place again.
