For all appearances, it seems like a narcissist just shuts off their emotions for other people. Yet, in all actuality, there was never any emotions to shut off. The narcissist simply stops playing the role of caring for you. You no longer serve a purpose, they’ve met someone new or maybe you hit their ego in a negative way. Plus, we all know how deep it cuts us when someone we care for on such an emotional level doesn’t feel the same for us any longer. For some people, having the power to hurt someone that deep or to cause such an emotional upheaval in the life of another, gives them an intense feeling of power. They give you the feelings of joy, happiness, LOVE….then they take it all away; only to let it be replaced with hollowness, loneliness, emotional despair over your loss. And they are well aware of the fact that you are left feeling broken and half dead inside because they have shut you out and remain cold towards you. So, as hard as it is to face, we have to recognize that this person never held any actual feelings or regard for us as a person. They only cared about what we could bring into their lives. The person you met and developed true emotions for never existed. They only played the part that you wanted to see.
