Some therapists are very uncomfortable handling transference. Some don't even believe in it! That's rarer nowadays but older therapists might still have the belief.
But in my unprofessional opinion it may essentially "freak" therapists out. Even though it shouldn't. They are human.
I've used the transference I have with my therapist to learn a great bit about myself. This is why. I have negative transference with him, meaning I can't stand him most of the time. We have successfully linked this back to the fact that I see him as my abuser, which we also linked back to the fact that my therapist is controlling in some ways and that's where things go wrong with me. It's such a topsy turny thing. IMO on my end my therapist was transferent first. And I counter transferred. He played caretaker, because my situation was "damsel in distress" and caretaker equals control. And now I hate "him" for it. Because someone controlling me is the absolute worse thing I could experience.
This led to being able to see why jobs never worked out. Why I would leave them quickly, because I can't stand having a boss stand over me. Why I've never had a boyfriend, because I don't want to "belong" to someone. Why I'm so antidependent and cannot ask for help, ever. Because I would feel as if I owed someone something and I can't take feeling as if I have to be needy, because it makes me seem less powerful and may result in me being victimized.
But honestly because imo my therapist was transferent first, there was a long period where we didn't talk about "it" at all. And it was very frustrating dealing with it on my own. I would bring it up and he would avoid. Because it required seeing flaws in himself. (being a rescuer). Finally after a year of this and me being patient, because I really wanted to learn from my experience he admitted that he felt the need to rescue, control and take care of me. None of which I wanted or enjoyed. But we both learned from it. Ts are people too and have their flaws also. You can go through therapy your whole life and still find flaws. It will take one patient to "scratch the itch" and then they learn too.
You might have scratched your Ts itch.

And she wasn't comfortable with it. Does it make it right? No. I don't believe she was purposely having an intent to harm though. She, like anyone else isn't ready to face some skeletons, so she referred you elsewhere.
