Punkin, The ultimatum for help may have helped him to make a decision about walking and chickie poo. Mlcers do not want to be told what to do or what is wrong w/them. Yes, you were the wife living under the same roof, but he was entering the MLC zone. He didn't want a mother.
As for awakening from replay? There is depression and withdrawal. He will awaken when he's completely through the crisis and ready to be brought out of the oven. He's got a long, long way to go.
I would just leave him be and have contact w/him only when it is an emergency or about the family. He's got to work through this stuff on his own and in his own time. You have to turn your focus on to you and what you need to do in order to survive.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
