Narcissists are empty inside.
A narcissist doesn’t have a true sense of self.
They are mirroring you. They don’t have a solid emotional foundation to build a long-standing personality on. So, they mimic your personality, your speech patterns your sense of style, etc. This mirroring act is found in many toxic type of personalities like psychopaths too. They are chameleons; you can never see their true colors. In fact, they don’t have one. If the narcissist doesn’t base his personality on someone else’s, they won’t have a personality! They are incredibly empty and all they have is a bunch of mind games.
You have to understand that you weren’t an easy target. You weren’t played because you are weak but actually, you were targeted because you had so many good traits that the narcissist envies and tries to mirror.
