Well, there's no telling what he is thinking. Or if he is thinking!
He could well still think he wants a divorce. There's nothing you can do to snap your fingers and change that. And it could well be that for now, he thinks this is a perfectly acceptable way to live. But it seems to me that he is questioning that. Of course, in an MLCer that can go on for a while, and he can flip-flop at the drop of a hat.
All you can do is take care of yourself. At some point, you will have to decide if you can forgive the A, some can, some can't. In my opinion, the good thing is that you don't have to decide until you are ready to. Keep breathing. Try to be a better you every day. And don't try to rush yourself into anything.
