If your therapist is CBT it might not be a good idea, but most other types of therapists understand transference. If I were you, I'd talk to him about it. The fact that you have transference like that is really significant. I think that if you just abruptly stop, you might continue on with unresolved issues that interfere with your life. I had big time parental transference with my therapist, and it was the best thing that ever happened to me. She knew what she was doing, and used it to give me that healthy relationship patterns I should have gotten in the first place.

Not bringing the transference into the therapy might be why you're stuck. But again, if this is a therapist who doesn't "believe" in transference, then you might consider just finding another therapist.
