Dad, the reason she there waS no talk of your marriage during her call is because she has everything right where she needs it.
A compliant and free babysitter so she is free to go to work,or go out with her fella.
She isn't interested in progressing your marriage or fixing it. But as I have said before, denial is part of the grieving process so take all the time you need.
Just don't stop doing things for yourself.
Take care.

Profound, did you consider that his messing around has stopped because your separated and he no longer feels driven to go out and do these things.I might also be inclined to say cheating is something you are inclined to do or not. It rarely changes.
I find rarely does returning to the previous failed situation result in a new out come. Still all the best,
