I don't think a man would walk away without knowing what he is doing and why. And To say a man is a coward is pretty harsh really; if you don't know his thinking or his story a little understanding might be better?

He should take the contract back to court to have it changed if it is too hard on him and by the sounds of it, it is. Forget the ex and focus on your bf and what he really wants; maybe in his mind he just wants peace and feels he's being attacked from all angles.

I really wish you the best
