It is not for a therapist to decide what ought to be important for a client. If you say you don't want to discuss a particular aspect of your life, then that is your choice and your decision. The T has no business invalidating that choice.

I have told Ts in the past that I did not want to talk about areas they thought seemed important. They have always respected that, though I ended therapy with two previous therapists anyway. I don't see how meaningful therapy is possible if the therapist does not respect the client. They might not agree with the client's choices, but it is part of their job to be respectful of those choices and not force their own agenda on the client.
