I am not a mean, angry, vengeful person and I experience great feelings of guilt afterward. In fact, I really only have those feelings about my children being hurt by their father, maybe because I fooled myself into thinking the pain would stop once he was gone.
Getting the last word w a narc. Rejection. We want closure which is never going to come in a way that we want but we can find closure by No Contact. We want to be heard, want them to know the pain they've caused but they are never going to listen and if they do, they don't hear the words. What we often miss is the beauty of No Contact. You are finally saying No More. It is your voice without the words but they hear it loud and clear.
They love to project their own faults onto you, especially if you confront them. If you dare to explain to them they are a Narcissist, they will simply turn around and call you one. They will say anything to convince you that you are the one with the problem, not them. Ignore their bullshit. Just go no contact. Its healthier for you in the long run. Even trained psychologists know there is no help for a Narcissist. You can't fix them.
