My family (my daughter, specifically) is currently going through a difficult time because of the behavior of her former boyfriend, who, (theorizes her counselor and several of my psychotherapist colleagues) is likely a compensatory narcissist.

I am familiar with the traits of a classic narcissist, but this young man doesn't have the overt bravado and confidence usually associated with the disorder. Instead, he yo-yo's between pompous over-confidence and utter dejection.

What has been your experience with this type of disorder?
