Peace, You are the second poster to ask this question about connection this week. The answer is...it depends upon the person and the situation. Some stay connnected throughout replay, but you have to remember that depression comes along and with that....withdrawal. The withdrawal is more evident closer to the end of the replay/depression stages.
Stop and think about it, money, euphoria and fun are gone. All he has left is bills and down time. Depression is back in full swing and he has no where to go but to the " hit bottom" stage. If you read up on depression, especially the dark depression, you will see he's doing the withdrawing. This is very natural. Leave him be, do not argue w/him. Walk away if he begins picking fights for he's very angry w/himself and everything that he's screwed up.
It's a long ride and one that you will need to step away from, especially at this stage. He needs the time to think and figure out when he wants to grow up and how to resolve the mess he's made.
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.
