It is difficult to make a diagnosis based on the sparce information available in the post. Yes she certainly sounds like she is a narcissistic personality disorder. The only way to discuss these issues is straight forward. The reaction in all probability will not be positive given her presupposed narcissism. Candidly the outlook is grim. Personality disorders are extremely difficult to impact upon and change even with therapy because the individual is so well defended that they do not believe that there is anything wrong with them. In such situations, the truly only realistic alternative is to change your reaction to her narcissism. You will have to swallow a great deal and accept a significant amount of abuse. This is a value judgment that you will have to make. Is it worth it? I hope that this has been helpful and i wish you the best.
