Has he totally reconnected with friends, co-workers and family? Has he started taking a real interest in what everyone is doing? If this is true reconnection, you will be the last one that he reconnects to, i.e., just as you were the first he disconnected w/many months/years ago.
It sounds to me like he wants to be friends with everyone. Is he trying to smooth things over for not being around during the holiday? They really do have a way of trying to knock us off balance, but you are handling the situation well. I think that in his own way, he doesn't want a divorce, but can't come out and say it to you. He has to save face w/himself and others.
Time will tell if this is true reconnection or not. Keep your expectations at zero and continue on w/your life. If he's waking up, he's going to have to paddle quite hard to catch up with the growth and experience that you've gained during his "OZ" visit.
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.
