This is a straight up abuse of power.

Also, if a professional can't help here, why does she think you can? Surely there are more people she can contact. It sounds like she has VERY poor boundaries. And the attractive compliment is a no-no. If you have any co-dependent tendencies, beware the waif behaviors. She's a grown-*** woman. I'm sure she can pick up the phone and call a few people. A local church. A community organization. Someone else other than her THERAPY CLIENT.
