My thought when I first read that your T had blocked again was that it was a passive aggressive strike at you because he was still mad about your "abusive" behavior towards him and the aftermath. I know that's reading a lot into it, but it aligns with my impression of your T from all you have written.

MUE, so often when you write about group it is about these blow-ups and problems and how you feel bad and upset about what happened, etc. You seem to spend a lot of time thinking about the bad events of group and dreading going to the next session. It just seems like such a big negative, and not what is helpful to a person under a lot of stress with lots of real life problems, like your XH, to deal with. I have wondered why you go, and what bloom said about wanting to please others made me think that perhaps that explains why you go--to please T? If you quit group, would he be angry at you? It seems like you also spend time in individual therapy going over group events instead of working on your main therapy strand, so it can slow your progress there. I have a bit of distrust for therapists who get their clients to sign up for their groups. Are they just trying to fill their own group instead of directing the client to the most helpful group? Did you and your T ever discuss what sort of group would be most beneficial?

MUE, I am sorry if I raise somewhat negative questions. Often when I read your posts, I feel this unease about your therapy situation. I want better for you.
