It's difficult, but you can do it....treat him as an old friend. Do not inquire about the ow or what he is doing. If he wants you to know something, he will tell you. They tend to have loose lips during MLC. Continue doing what is working for you, but keep your expectations at zero.
I think he's having some moments of sanity and is "dating" you, just as he would any other woman (as if he were single). They call this comparison shopping. Some of them will do this. I don't know if that's what your h is doing or not....only you know your h.
Please keep your expectations at zero. As soon as you get your hopes up a little bit, he'll slither back into the MLC fog. Their radar is extra sensitive and can detect your moods, etc.
Try to keep the focus on you and your family.
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.
