Can I challenge you a little here?

If your answer is no feel free to read no further.

YOU JUST WENT TO HAVE A SESSION WITH YOUR THERAPIST'S THERAPIST? Just like that?

And you have feelings for your therapist?

In your heart of hearts, what were your motives in going?

Of course you're within your rights to see any therapist who will see you. But come on. IMHO there is a lot more to your actions than you're copping to here.

Also what on this lonely green planet was your therapist doing telling you who they see for therapy? That is some intensely effed up oversharing! I am deeply concerned about their professionalism.

I think this is one dangerous game and the therapist was absolutely right to put a stop to it. Though I do think they probably should have declined to continue to see you without revealing as much as they did. As to the limits of confidentiality, I cannot comment on that intelligently except to say that it strikes me as somewhere on the spectrum of precious to galling that you knowingly went to see your therapist's therapist and you feel that YOUR boundaries have been violated.
