That group does not sound supportive period. Which kinda defeats the point, despite the familiarity.
Unfortunately, I also understand where the facilitators are coming from...a history of abuse can be hard to deal with in a group, where the other members have their own issues too. It IS a lot in that setting.

I was in an outpatient program, where my caseworker told me that similar rules were in place. Since it was connected to a hospital focused on the care of each patient, there was some leeway (couldn't just be like "your treatment ends NOW because of *this* limit")...yet she saw that I was strugging with a lot in the past IMPACING the present too. So she also refered me to another group when I was done treatment THAT SPECIFICALLY FOCUSED on abuse. I've just started that 1 now...

Would it be possibly to find support groups in your area with that focus?

I'm sorry your struggling right now...
