Narcissists are notorious for discarding you and then hoovering around to keep you wrapped up in the relationship. One day you are their soulmate and the next day they don't know you. However, when you decide to break this pattern the narcissist will go out of their way to keep you invovled. At first this could be by saying "but I've changed!" and they shower you with affection again.
If you stick to your guns and continue leaving the relationship the narcissist will get down right dirty. Narcissists will spy on you, tap your phones, hack your computer and personal accounts, break into your home and steal sentimental items, stalk you, harass you, and down right make your life a living hell.
If your narcissist is hoovering then be prepared to get a restraining order because things are about to go from bad to worse.

Ex wife is the narcissistic stalker,communicates via triangle gossip,shows up at " family"funerals,dinners etc.thats because as the scapegoat,the family system discarded me long ago, as she did.
However, I avoided the triangulation trap ,and avoid them as much as possible.there is a saying "“When people show you who they are, believe them the first time. "
when you are mistreated the first time, when someone shows you lack of integrity or dishonesty the first time, know that this will be followed many many other times,
