I glanced through the other thread and all I could think is that you are a doormat for him to wipe his feet on. "Hi honey, how was your day?" all sweetly does not apply when dealing with an angry jerk like your husband. Coach got back together with his wife...why? Because he changed and she liked those changes. Your husband doesn't even deserve to come back...what do you want him for? Miss being his emotional/verbal punching bag?
In the time since you first wrote I don't hear much in the way of you detaching from him and moving forward. Don't ask about his bad day. Change the locks so he realizes it isn't his house any more. Can you walk right into his place without a knock? Don't be available to him. If he starts to go ballistic on you, walk away or hang up the phone (whichever the case may be), but mainly don't put yourself in a situation where he can go off on you. He's the one unhappy with life and with you....so why isn't he just staying out of your hair?
