Well, at least you realize that he is a manipulator, so, as hard as it may be, don't let him manipulate you. I know they frown on this around here, but what I'd do is have NO contact with him while he is in there, and figure out what I really want. You need time away from him on all fronts so you can get your mind clear and look at things in their proper perspective. The more time you have away from his manipulative influence, the clearer things will become and you might just realize that you don't want all this crap in your life.
