Law #9: Leave a brutal impact on your victim so they always remember you, even if they did not desire you in the beginning.
Inflicting trauma is one of the narcissist’s few natural talents (the others, they just steal and fake from meeting actually talented people). They know that the bigger the trauma, the more memorable and significant they are to you and your life, even if you were never interested in them. It’s not your hatred they fear – it’s their insignificance. Once they lose control over you, they lash out to try to regain that significance just to re-traumatize you all over again. This can traumatize you even if you weren’t that interested in the first place.
