Being Me, the reason he does what he does is to suck you back in. He knows how far to push before he pushes you over, on the other hand, I think you are going to have to find a way to make the best of things, as I really don't think you intend to separate. I'm not putting you down in saying that, I just have a feeling you won't. If that's the case, you need to find a way to be happy in the situation.
