I know you are seeking answers, but the description of the stitch is vague. She apparently hasn't given you much to go, other than dissatisfaction with the sex life. Did you share the same opinion?

Women who won't talk about the problem and go straight for D can be hard nuts to crack. There have been a few stories here where the man had no clue anything was wrong, and one day the W leaves without a word......and gets a D. I can't imagine how crazy that would make me, never knowing the reason behind it.

I don't know how to advise you about the physiologist session. IMO, the WAW has to be open and cooperative in order to accomplish much. Otherwise the C is dealing with her resistance. Did the court choose this C or did you?

I hope the C is pro-marriage and one who will give solutions. But there are some who actually encourage D and say go find your happiness.

Maybe just let the C lead the discussion, instead of you appearing to take charge. Answer the questions directed at you as honest as possible. If she sits there and won't talk, let the C deal with it. But don't talk for her. That's very important! The C should know how to deal with a resistant introvert in sessions.

It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
