Narcissists are known to be master manipulators and liars. They're never willing to accept accountability. When they're caught in a lie, they will more than likely shift the blame your way and call you a liar. Even if they have to make something up or bring up something that happened a long time ago that has nothing to do with the current situation. Don't buy into it. It's just to shut you up. They don't like to be called out. It creates a narcissistic injury. You have to ask yourself, is it really worth the mental strain? Or, should you just finally accept the fact that you're with the wrong person, if it's a romantic relationship. Or, do you have the wrong job? Or, do you need to close some chapters in your life to move forward? Here's a little encouragement. I wish you the best! Peace & Blessings to you!
