I have had similar (but not identical) types of transference creep up in many of my relationships going back a very long way. For me anyway, there's an underlying issue, some kind of intense need that underpins this process and I find it both tremendously unpleasant and nearly impossible to escape. I think that almost undefinable yearning is a big part of why I need therapy in the first place. So there's really no running from it I think in my case.

The only time I would suggest switching Ts rather than addressing the transference and working through it is if your T cannot or will not process it with you in a safe, supportive, nonsexual, non-shaming way.
