I see a t who at one time was seeing me for individual and us for marriage. He was careful to not disclose things that I had said only to him.

I think it is fine to ask your t exactly what was said, but I would be surprised if your t said much beyond the fact that she has a client who wants to keep t and marriage counseling separate and that she had made the referral. It would be weird for her to say that she was referring you but you need to keep [...] from H. I don't think your t would share your secret with anyone. But definitely ask to set your mind at rest. I don't think I would want to reveal something that private to a counselor that I didn't even know.
