Is it possible that your interpretation that "he is annoyed that his 8 months of modalities has not fully fixed me" is incorrect, and that he said this in a spirit and/or context of something else? For example, I could see how someone might say this if they perceive a person is stuck and unwilling to consider doing things different. Perhaps he thought you were unreceptive to thinking about this differently or attempting to do it differently, as in "I must do things this way." That is what your post sounds like to me, and of course my interpretation may well be wrong.

I have found it useful to tell T what I thought from what he said, which if I'm irritated or insulted I think I am always wrong. Then he tells me what he was thinking and the context reveals itself for what it really is, something deeper and more meaningful, both for the relationship and in terms of understanding myself.
