I read somewhere that the mark of a narcissist in relationships is the constant "place a person on a pedestal" versus "person being the worst ever" when I was trying to figure out my narcissistic tendencies and if a more distant lover was a narcissist. I have seen this, been on the receiving end of this, so it doesn't surprise me when it, again, happens. I have been on the giving end of this, and the thing I find most important in these situations is to not deny the love you have for a person even if you feel badly about them. It only serves to damage both parties.
