Short version - I think this is common thing for those in therapy. Also I think that the therpists are trained to look for it. She's probably already aware of it. If you feel it's interfering with the therapy, then it probably should be discussed. A way to do it might be to ask something like, "Tell me some about
the therapy process. Is it common for those undergoing the therapy to feel like they might be attracted to the therapist?"
I think as part of the ethics of being a therapist, she can not have a relationship with you. It's a conflict of interest. People who are in therapy are particularly vulnerable and stuff like that.
