I feel like the best solution to getting away and dealing with a toxic narcissist is to just go cold turkey and ghost them, just completely leave and cut them off from your time and energy! Even when time passes, you get better but the narcissist thinks you will believe they have changed (which is childish and immature) and that it‘s your problem why you left them (who cares!). Every time I moved away or ghosted a narcissist I don’t have to deal with them and I can live my life!
