I hate the idea of changing and starting from scratch. This T even drove me to the hospital once. But I also hate the idea that yes, he will maintain confidentiality but as you said he is human and will form opinions about us. I don't want to be sitting there thinking that as I am baring my soul, he is comparing it to what my ex is saying about me. Situation sucks. My ex had seen someone else for a few sessions but said he wasn't't getting what he needed. Chances are that T called him on his BS so he went to my T who he had seen with me now and then over the years and their relationship was based on the fake persona of his being a great guy victimized by my bipolar *****iness that he put on when we had couple's therapy.
What a mess.

I am not sure if you all know the back story but while we were married he was somewhat emotionally abusive calling me the B word and then saying it was a joke, and living a secret life making hook up dates with women, men transgender people and escorts. He ran ads on Craigslist looking for people to hook up with and offering his services as a driver for escorts to make extra money or to trade for favors. All the while claiming he had no interest in sex and going to couples therapy pretending he was working on the relationship. When I found out about his secret, I told him to leave and we got a divorce, sold the house and I moved to a new town. He almost tried for custody until I told him that I had given my attorney printouts of everything I had found online including solicitation. His friend, the owner of the school my kids went to and where ex works, tried to get my oldest son's father go for custody too, but he is a good guy and told me about it.
Everything is done and settled and if I didn't have to interact with him as my son's father, he would be entirely out of my life. So to have him spinning his lies to my T is a problem for me.
I want my safe haven back. By the way, my T knows all about the lies. My ex needs serious therapy but he should be made to go to someone else.
