Well, my therapist is a woman and so am I so I was a little confused at first when I "fell in love" with her. I had the courage to bring it up in therapy and she was wonderful about it. We discussed how it related to the emotional/physical abandonment issues I had around my father and that I needed to be able to really trust her so that I could work on my core issues.
In many ways, I see her as a mother/aunt/older sister figure and when I start thinking of her in a romantic way, I know that it is part of the process.
Someday I want to be able to transfer those feelings to a romantic partner.
Hope this helps!
