How attachment styles influence narcissism

Thanks for the article - yes, I suspect that at both extremes one can find co-morbid factors. I was wondering if it might be more like Borderline for AP, but I do get that Covert or Vulnerable Narcissism fits the extreme AP behavior too. The AP I know seems convinced that her crush is Avoidant, but in fact he has no interest in her and I gradually realize that she is stalking him, on Facebook and in real life, showing up where he is, using pretexts to visit his home, etc.

Even though she is very intelligent, she seems to have no idea that she is trespassing on his boundaries.
