It sounds to me like your T might have developed some insecurities about whether she’s being a good therapist. I personally find a bit of self disclosure on the part of the therapist helpful. You describe it as being a weird kind of rupture, and I wonder if you have the expectation that ruptures would be ‘caused’ by the client. In my experience therapists tend to be imperfect and to bring their own insecurities or stuff to the relationship.
