I would go back one more time to give both of you a chance to talk. I don't like the way she handled it but maybe she would like to explain? You would definitely have a better idea after one more session.
I told my T about my MET and she handled it well. She's not a T. to really validate feelings - she doesn't want me to be dependent on validation from others which I am right now. But, she has been willing to explore their meaning and talk when I'm able.
