I am concerned about the reporting issue as well. Your history with your previous T is over and done with, but if what Sue's telling you is accurate, her therapist is crossing a line and should theoretically know that, and if your T knows them she may have a professional duty to intervene at some point. If that's the case maybe she can handle it through official channels, so it doesn't affect your friendship.
