I had this experience. I told him he'd changed. He didnt think so, of course.
All I could say was, "well the impact you have inside me has changed. " This, of course no-one can refute.
My T. did say, somethin like "perhaps its because I know you better, and you're taking that as a bad change." It was a good try, and came from a sympathetic place. But something more serous, something negative had taken over, thats what I experienced. So, as my memory has been unwinding the moments, I've been writing them down. So, I have a record, this is not in order to try and convict T. in my head, its to keep my sanity. And, one day, maybe truth and reconcilliation will be arrived at.

As a person of competence, caring, and gentleness, what approach do you think would be best for you to take when you go there? like, what stance inside yourself would you like to have?
.(.. as difficult as it is when with a T. )

.. .. dunno if this helps any..??
