I think the more important part to have W focus is on the maturation stages of love in a marriage. PEAs is only one part. It does not help you and W move forward.
Isn't your MC working on a solution-based approach in getting you two to recognize that the early phases of a marriage is one of lust and excitement because it was all new and exciting. Then life happens: kids, mortgage, etc.
To me, I am chiding the MC in a way for not really pointing out the obvious when it comes to mature love and working on nurturing the marital throughout the course of the M.
In my mind, I do think you two need to draw up a plan to find your way back to the M. Especially for W to realize that all marriages go through ups and downs. Marriage and conflict does go hand-in-hand.
As for the "sundown syndrome" in your M, I'd make notations in a solutions journal, for say, 2 to 3 weeks. This way, you'll be able to see some clear patterns and figure a way out of them with the help and guidance from the MC. The cycle needs to be broken some way.
