wow, that sounds really unprofessional! It's also (possibly) a huge breach confidentiality, but definitely unethical! I would either confront him about it or (depending on the breach of confidentiality piece) report him to his supervisor or the licensing board about it... I would also be hesitant to talk to another T after hearing something like that. Most T's have better boundaries though, and are more reliable (at least in my experience)...
