Narcissist cannot love, they cannot show empathy or emotions, they cannot show remorse or regret because they project these emotions unto others by mirroring them. I always classified my narc personally as a “chameleon” because he could change like the wind to better suit any situation. Things he once disliked for years he suddenly will like to impress a new supply(though its short lived). You will begin to ask yourself who is this person I thought I knew? This is common and you probably will never meet anyone as good as narc who can lie and be so convincing that they’d fool even the best therapist. A true “con” was once my classification used in describing my narc. What terms might you have used to describe his or her behavior?
