I would cancel. I can understand not being able to provide reviews because of confidentiality reason. I have asked my therapists why they bacame a therapist and in the very beginning they gave vague but acceptable answers. Like I was the person growing up who everyone went to for advice and was encourage by teachers or whatever to consider becoming a T. After working with my Ts for a while they gave more personal information.

The last part would totally have turned me off. He could have said I appreciate your questions but I would rather discuss them in person rather than over email. He handled it poorly.
