Most schools of therapy require you to be in supervision in order to be practising safely and competently. I know that in private practice people can essentially do what they want but it is definitely not considered the norm to only consult a supervisor when you feel something might be off, since part of the whole point of supervision is getting an experienced third party to help you identify where your stuff is getting in the room but you are not really aware of it. I wouldn't see a T who didn't attend regular supervision. The idea that he didn't want to consult a supervisor doesn't really sit brilliantly with me.
I'm sorry it is such a hard road for you Liese. I don't think you have expressed anything unreasonable. I kind of feel that this loop you get into should be the most interesting thing to him, not something that keeps getting shut down. I highly doubt you bring this stuff up unnecessarily - if it is important to you then to me it feels like legitimate therapy material.
Like others say, I also wonder whether you have reached a new developmental stage in your journey and it is a step he can't take, because of his modality, personality or own personal stuff.
