Not sure deceived is the right way of putting it. How would know what the therapeutic relationship is even going to be until a few months or so in? I knew going in I had an issue with becoming very attached to therapist. That is not my T's fault. He keeps all sorts of boundaries and has been nothing but professional but yet time and time again therapy shows me what I am lacking in my own life. A true emotional connection with someone. I understand that this type of connection goes deeper with a therapist then it could ever with someone outside the therapist room because of the "paid" job aspect.

It does feel like a "Physiological Prostitution" but my symptoms I went in with have improved so much but I am not sure they would not return if he terminated me right now. I know connection and relationship with him are the reasons for my improvement and right now I feel if he terminated me that is where the harm comes in.

Your post talks about deception. I do not think it is deception. Deceit would be if the therapist knew exactly what would happen prior to starting therapy.
