Narcissists lack self awareness and overestimate their empathy. They know hitting you is wrong and may even know it hurts , but they aren’t motivated to care and often feel the victim deserves to be abused , devalued and discarded.
They don’t want to hear your anger or complaints about their behaviors so they devalue your character, spread rumors to those who would offer you support, and discard you in the most cruel and calculated ways, making you believe it your fault that the relationship is ending.
Narcissists want to do what they want to do without anyone telling them different. They are childish, scary and think they are superior all at once. If you continue to stay you will be abused more and more with less good moments in between.
Do your best to learn about narcissistic abuse and patterns and get away. Find support and trust you aren’t alone out in the world. Keep Healing regardless of the chaos because you deserve your contentment and peace in life . Stay Strong.
