Narcissists feel empty inside and they lack confidence, despite how they look and what they might have. They have loads of insecurities and project them onto their victims. Stop giving up your power by not engaging when they come for you. Go no contact if you can. If you can't, go gray rock. Give the simplest response. No matter what you say, they only hear themselves. You're just an object to them. Protect your peace and mental by planning your exit asap and leave them for good.
