I don't remember my relationship with either of my therapists effecting the marriage much. The marriage was in decline. My XH didn't really know when I was going to T and I didn't share with him about the details of therapy. I felt like it was none of his business. He hadn't been concerned with my wellbeing or happiness for years, so I didn't see that he had an interest in my therapy or a even a right to know about any aspect of my healthcare. Going to see my second (current) T, in particular, helped give me the strength and courage to end the marriage. My XH did do couples therapy with me for a while with T, and at that point I think he saw what a good relationship we had. He didn't seem judgmental about it one way or another, but I wonder if he measured himself up against T? If so, his emotional deficits would have been glaring. I wonder if he felt that? My T, who does a lot of couples therapy, told me that many spouses, men in particular, feel really glad their wife has a therapist when the marriage is ending. Men are socialized to feel they need to provide for and take care of the wife, and many feel guilty if they are the ones ending the marriage. So it can help them to know their wife isn't totally alone and has a T to help her make it through the breakup. I don't know if my XH felt that or not (plus it was me who initiated the divorce, not him, although he was OK with it).
