The lesson that Iโve learned about narcissists is, you will never win. At the end of the argument itโs your fault for voicing out their mistakes. So, just let them go!
Best way to deal with a narcissist is not at all. Youโll get stuck in a never ending cycle of them provoking you and blaming you for your reaction. Your reaction becomes the problem and not what they did to you. Theyโll never learn, and itโll always be your fault. Just leave.
