I would suggest giving him lots of space. I have read where there is a grieving process when that relationship ends. For me, I don't ask any questions, am supportive, and loving. I do see some positives in my sitch. My H is also going to counseling too.
Definately keep up your PMA. You still want to DB and look like the best choice. You want to draw your H back.
I will be honest, sometimes this is harder than before. You think that when it is over with ow, that they will be back and working on your M. But, it doesn't happen that way. You have to keep DBing and work even harder than before. Get rid of any expectations you have. Give him time and space. Continue your 180s, be happy, and loving. Follow his lead, if he seems comfortable then what you are doing is probably on the mark. If he seems uncomfortable, then you are probably trying too hard.
I hope this helps. Let me know if you have any other questions.
