People with personality disorders like the narcissist may seem too good to be true when they are feeding off of your delicious fuel. But at some point, it ends, and you run dry. Overnight, they become savage butchers who know how to slice and slash their way to the bone when they are ready to devalue or discard and when they suffer a narcissistic injury. Prepare to bleed. It's nothing personal. None of it is really about you. It's just what they have to do. A leopard cannot change its spots, a zebra cannot change its stripes, and these magnificent beasts cannot change the fact that they are the most deadly animals in the jungle.
