The problem for me is the ambiguity. Therapists treat you like a trusted friend, or their child, or even a love interest in some cases, but then remind you that it's a business relationship and don't get any crazy ideas.

People talk about the importance of boundaries in therapy, and yet therapy relationships in my experience are poorly defined and cross all sorts of boundaries in their basic nature.

I do think it is odd that your therapist would declare openly that you are friends. On the other hand, if you removed this aspect of it, what would be left? I'm not really clear what a therapist is supposed to do.
