I do think that my son's situation has something to do with it. I feel like if we ever get to the point of repairing our marriage - that will become a big issue in therapy. She has major guilt about not wanting to be with him. I know this from the past.
Right now we have a ways to go to even begin to broach that subject and try to repair it. My Wife has always "run" from emotionally heavy subjects.
We have TONS of great help. And we leverage it as much as possible. But for the last year leading to where we are my wife avoided us going out alone together as a couple. I now know why.
