Thanks for the feedback, everyone. I guess to clarify: this family member put my T and I in touch initially, so it wasn't really a breach of confidentiality to just say "thanks." I don't really see it as my T's fault. I am not at all happy with the family member but not sure how or if I will confront him. I am VERY curious as to why my T didn't bring it up with me--it feels strange knowing they had a communication about me of which I was unaware. Also, I am an adult and will tell my T what I want her to know--I don't need someone feeding her information from their perspective (sorry, ranting now).

Anyway, thanks for your input--it helped me to process this weirdness!
