Libby, He's not thinking....or should I say he doesn't care right now. He wants to show off his flat to his daughter. As for another step out of the fog? I seriously doubt it. They have moments of sanity and then go right back into the hole.
Please try not to analyze his behavior. He's all over the map and will be that way for many months to come. You'll drive yourself insane trying to figure out whether he's stepping out of the fog or what he is doing.
Keep the focus on you and your family.
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.
