In recovering from abandonment or betrayal, learning about destructive narcissism can help you heal. Naming this brand of emotional abuse opens the door out of denial into the facts of what has happened.
What a relief to realize you are not losing your mind. Nor are you alone in this unhinging experience. It is not all your fault, after all.
It gives you back your ground to learn such charming, yet disordered personalities exist. Those who learned to survive by undermining and shaming others. These people pull you in with charm and attention, then begin to devalue, ignore, insult, and often discard you.
While you are caught in this web of gratification and hurt, pleasure and fear, you hardly see it. The slow-drip confusion and pain of emotional abuse breeds denial for self-protection.
