I would ask what exactly she meant by "fall in love" with her. Is she just using that as a term for completely trusting her? Or does she actually mean more like what falling in love is?

I had some paternal and some erotic transference for my marriage counselor, and we worked through it (though it was painful at times). And a bit of maternal transference for my T. But those developed naturally as a product of therapy and realizing some of what I had been missing in childhood and from other relationships. If one of them had actually said, "fall in love with me!" or "please develop intense transference for me," then that would have seemed weird.

So that's why I think you should ask her more about what she wants and why she thinks it would help you.
