Thanks for the responses everyone. I've calmed down about this some and realized that I have done all I can do at this point. She has not called me back so either she has already called him, or she hasn't but is still going to despite my wishes, or she hasn't and is going to respect my wishes. I suspect that the other T has some loyalty to my T - perhaps he has been a mentor to her? But I can't imagine starting a therapeutic relationship with her now. So, cross that one off my list.
