Narcissists thrive on drama and being the center of attention. They like to have the control and often play the victim role because it provides attention. They are users and tend to have a patsy list of individuals they can turn to for a feed. If they don’t get the feed they feel entitled to they distance in search of a place they can get their desired feed. It’s typically an effort to make up for a lack in their childhood.
So just become boring and unaffected by their drama and they tend to distance to find it else where.
