Thanks for all your good advice. Update: W talked it all out with our MC in a private appointment. Then a friend who's going through a D because her partner of 22 years is having an A came over and cried and was so miserable. It gave W a chance to see the pain As cause. So both the therapy and this realization have made things better. W is trying, and so am I.
And I'm reading MWD's book on infidelity and finding it incredibly helpful. I wish i had it 6 months ago.
