I think transference can happen with someone other than a therapist, especially if it's someone in a position of authority. I had a really strong transference to a priest, and I realize I totally idolized him. It lasted for about 7 years, and then I found out he left his wife and I was so mad at him. That was the end of the transference. I trusted him, and we were quite close, and when he found out that I knew, he told me he wasn't ever going to tell me he had left his wife (she went to a different church, but I also did get to know her and like her a lot). She was the one who told me he had left her.
