In the context of my relationship with T, the "I miss you" comment wouldn't go too well. I guess it really depends on the relationship. I prefer to know that he is concerned, or that he saw a quote by a certain writer and it made him think of me. Things like that. I'm not saying that "I miss you" is a right or wrong thing for a therapist to say. It really depends on the nature of what's normal for your relationship. I can't even really answer in regards to what I would think if my T said that only because I know he wouldn't. It's just not something that would fall under the nature of our relationship and interactions.
