Sis, It doesn't sound like your h is completely out of the woods yet. They do tend to distance themselves from the spouse if they've gotten too close for their own comfort. As for the ow, the jury is still out on that one. They could have had a disagreement, therefore he was being a bit more friendlier to you, etc.
Do what works and if you aren't sure what to do, then sit quietly and the answers will fall into your lap. What should your behavior be at this time? Why, just be yourself. If you are friendly towards him, continue to be that way. Treat him as you would a neighbor who comes calling for a cup a of sugar. Keep your expectations at zero or one and don't expect him to do things that he normally would have done pre-ow.
He's truly not thinking about a divorce at the moment, but I you begin to question/challenge him about what's going on or have relationship discussions, the word "divorce" will crop up again. He's content w/the way things are for now. I would suggest that you continue to observe his behavior and truly listen to what he has to say because they do tend to tell on themselves...but you have to listen and sift through the words to get the answers.
Reconnection? I don't think so. I think he's just a very slow one that is taking his time in figuring things out for himself. At least that's what I am getting from your first posting. You'll have to share a bit more of what's going on in order for us to provide additional and/or better advice.
For now, keep the focus on you as much as you can and continue as you have been...because something you are doing is working if he's not screaming for a divorce.
