You see, this is one good reason it's better not to develop friendship with an ex-T. Friends can say things like that to each-other and call it honesty and being open with feelings, but it would likely always sound awful from a T or ex-T.

My first T blamed me and my "transference" (that never existed in the form he claimed it) for everything he was not able to deal with and became extremely manipulative in the end. He never behaved that way earlier in my therapy, only when we started having conflicts and I expressed dissatisfaction with a number of things. He just wasn't able to handle his failure and projected all sorts of crap onto me. I am not a very sensitive person in general to other people's BS but that made me mad for a long time, because it was so unfair. It is hard not to take it to heart but that's what I would suggest, if you can detach yourself from this Ts influence somewhat at least. You acknowledge yourself that he wasn't a very good therapist for you to start with and probably not the kind of person whose opinions deserve too much consideration now. It is definitely not you who is worth little but this guy as a professional!
