Well I guess none of us can know, you included if things will work out positively, but I think it is possible they will. i think the sentence 'have you ever thought I may not be the right therapist for you' was quite probably not him making a suggestion (did he say those actual words? With my T I have found that I have paraphrased what she said to me and changed it slightly and altered the meaning). It is more likely he was asking if that is what you were thinking? You have the sense that he is a good T, so it is likely you will be able to talk about this al and eventually reach an understanding. Therapy is full of ruptures, and maybe the ruptures are the most important bit, if we leave at the ruptures we'll be leaving at the best bit.
