Today in my session with my therapist, he pulled out an e-cigarette and started smoking it in front of me without asking me. As he started doing that, he also seemed to get more relaxed, leaned more deeply into his chair, and started inching his legs towards me. The whole thing made me feel really uncomfortable because he didn't seem to ask me about any of it. Is this appropriate behavior for a therapist, and if not, what should I do about it?
