Barb,
Sounds very good to me. I'm grateful for this change of attitude in him.
I think the best thing you can do is continue to work on you while he concentrates on his life. I know when my AD was in rehab I was told to fill my life with as much recovery as possible because I also needed to be as ready as possible when she came home. So if you don't go to meetings, I'd recommend adding them to your life. You can have double the support and recovery through face to face meetings and this board.
Hugs,
Hangin' In
