My most recent Ts have taken responsibility (or if not responsibility, explained their meaning behind what they said/did.) Often I have found that it is my misinterpreting their meaning, but they do admit that they could have been clearer about their point. But other times they admit that they made a mistake. I've never had them say that anything in the relationship is singularly my fault. It takes two for something to happen, they have shared the responsibility. Being that when I was growing up I was always blamed for everything that went wrong, I would not be willing to have a T who blamed me for things that go wrong. It would be like I was back living with my abusive parents.
