I think it all depends on what you hope to get out of the conversation. Do your feelings interfere with your therapy and/or daily functioning or do you just have a crush? Do you hope that he will express feeling for you or do you want them to help resolve your feelings. I think that's an important thing to consider before addressing the issue. I brought it up indirectly with my pdoc and he seemed to discourage me from addressing the issue. I think it also depends on the T snd how much they'd want to change the dynamic as well as you.
