I don't think I've ever said anything "hateful" to my T. However I did find that he finds it troublesome when I express my certainty that he will judge me about whatever I have shared with him. To me, it is about me and how awful and bad "I" am. His take on it is that I am judging him when I believe that he will hold something against me and he finds that insulting. I don't think he is that bothered by it but it was interesting to me that something I said was unintentionally hurtful.
