Having lived with and worked for a narcissist for years, I agree with Florence and dandylion. This behavior will not change, no matter how talented they are at manipulating people (you, the therapist) to believe that they will. Burning that bridge with my narcissist was like taking off a corset I didn't even know I was wearing; I could finally breathe again and my life is so much better for it. Although my body had been trying to tell me (a constant pit in my stomach), I had no idea how miserable I was until I was out of it.
