It is difficult to dis-engage with a narcissist. Probably because it seems important to have the record straight for a reasonable person. A narcissist is not a reasonable person. When you’ve come to the end of your rope, and it sounds like you may be ready, let go. And try to understand that by continuing to believe you can have a reasonable connection with an unreasonable person, you are not being truthful with that person. Be truthful, let go. It’s better to deal with your sadness because you stand a chance to save your sanity. Recite the Serenity Prayer, in its entirety, several times throughout the day. “Taking this world as it is and not as I would have it.” Find someone that has had to do this and let them help remind you that it is not wise for you to think you can fix a narcissist.
If you are able to successfully stop engagement you might be able to be a person that can help someone else with this difficult task. You don’t have to feel brave… just Be Brave.
