It certainly is one of those believe it when you see it type of situations. If he continues on this path with no one stopping him, he will end up in a very bad place and realize he only has two choices left. Personally, as much as his behaviour annoys me, I do not wish that fate upon him.
Really it would not surprise me if he is happy in his misery. As long as it gets him attention and people pander to that, why should he make an effort to get better? As much as it is his fault for not trying, it is also the fault of those who pander to this behaviour. I think that is the best explanation for why he is doing this.
I do hope that someone does something very soon before this carries on much longer. Neither of you can handle this continuing schedule much longer.
