He is only thinking about himself. Its a hallmark of the MLC/WAH syndrome. They are extremely selfish, only concerned about what is making them happy right now.
I agree that you should get professional help for your D, it cant hurt, look for someone who specializes in children of D. I often wondered how they could behave like this, we wouldnt have fallen in love with men who act as these men do. They just sort of lose their minds. Someday he will look at the flaming wreckage of his life and wonder what in the world he has done, I am absolutely certain of that.
You cant worry so much about what he is doing, and who he is doing it with. It just doesnt help you at all. I really hope that court went well, or at least as well as it can. Im not really sure why he would threaten to move back in, maybe its just an empty threat. Is it possible that hes looking for a way back in?
I just dont know what to say other than we are here for you and I hope that things get easier for you. Let us know how court went.
I guess I gave the wrong finger to the wrong man...
