S, First, you must remember...there's no way we can actually sit down and pinpoint a stage with these guys. They tend to flucuate between all of them except acceptance.
There's no way to tell why your h was over, but he came for a while. It could have been just a visit to touch base w/his old self and home, i.e., to reassure himself that it was still there and yes, even to be reassured that you and your son were there. When they are like this, yes, they are very uncomfortable in their skins. Remember...they are the exact opposite of who they once were and believe me, coming there and interacting w/you and your son most likely was uncomfortable for him today.
You need to take some time and read the MLC Resources again. You'll find the description and behavior of your h in there. He's very much in the skin of a pod person right now and you will not understand it for a very long time.
Learn to accept him for who he is at this time, keep your expectations at zero and treat him as you would a friend. You didn't fix him, therefore you can't fix him. Try to keep your home a safe haven for him. The more you do this, the more he will gravitate back to it. It's tough when they just pop over like that, but something tells me he wanted to make sure that everything was okay on the home front.
S, I know you hate to hear this, but keep the focus on you and your son. Right now, it's very important to just leave him out there. Please stop trying to analyze his every move and thought, because there is no way you will be able to do this. Why? Because he's an emotional wreck and they aren't operating in the rational mode.
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.
