I think that transference can be survived and worked through with a T who has very, very consistent boundaries, regarding how much they self-disclose, how much verbal affection or physical touch they allow, their out of session contact, and how they treat their various clients (i.e. they don't exacerbate transference by making a client feel suddenly very special in some way). This is an impression I've gotten from reading many threads here and from my own experience with my T, where I had transference (several kinds, both positive and negative) but it stayed moderate and was actually useful.

If your T has been professional and consistent, then you may be able to stick with her, explore where these unresolved needs are coming from, and have the feelings lessen in time. To me her consistency would count for more than her credentials or training.

I guess I don't really believe there are experts in transference. I just think there are good, consistent, professional, committed T's who can stick with clients and work through it, and then there are others who can't. So if I were the OP, I might try to go by how she's been as a T so far. Going off her cold turkey seems cruel though, I would try hard to alternate with another T for support, or see two at once for a while if at all feasible. Her offer to maintain email contact during the interim was quite kind and seems a good sign to me.
