I am in a similar sitch but no confirmed PA/EA although I think I am just fooling myself. And in the same house with a divorce on the way...
Don't look for little signs of life in the M as right now its just a smoke screen. I hate to dash your hopes as I was in the same boat and would be like "wow..she said something nice " and then I would be hoping for the reconciliation talk that never was gong to happen
Some of the folks here who have had positive results with the approach in your sitch have good advice
I don't recommend it across the board for everyone's situation becasue everyone's W or H is so different and so is the situation, but its good to listen to those who walked in your shoes.
