Educate yourself about narcissistic personality disorder. The more you understand, the better you’ll be able to recognize the techniques a narcissist may use to keep you in the relationship. When you threaten to leave, a narcissist will often resurrect the flattery and adoration (“love bombing”) that caused you to be interested in them in the first place. Or they’ll make grand promises about changing their behavior that they have no intention of keeping.
Write down the reasons why you’re leaving. Being clear on why you need to end the relationship can help prevent you from being sucked back in. Keep your list somewhere handy, such as on your phone, and refer to it when you’re starting to have self-doubts or the narcissist is laying on the charm or making outlandish promises.
Seek support. During your time together, the narcissist may have damaged your relationships with friends and family or limited your social life. But whatever your circumstances, you’re not alone. Even if you can’t reach out to old friends, you can find help from support groups or domestic violence helplines and shelters.
Don’t make empty threats. It’s a better tactic to accept that the narcissist won’t change and when you’re ready, simply leave. Making threats or pronouncements will only forewarn the narcissist and enable them to make it more difficult for you to get away.
Seek immediate help if you’re physically threatened or abused.Call 911 in the U.S, 999 in any EU Country, or your country’s local emergency service.
After you’ve left
Leaving a narcissist can be a huge blow to their sense of entitlement and self-importance. Their huge ego still needs to be fed, so they’ll often continue trying to exert control over you. If charm and “love bombing” doesn’t work, they may resort to threats, denigrating you to mutual friends and acquaintances, or stalking you, on social media or in person.
Cut off all contact with the narcissist. The more contact you have with them, the more hope you’ll give them that they can reel you back in. It’s safer to block their calls, texts, and emails, and disconnect from them on social media. If you have children together, have others with you for any scheduled custody handovers.
Allow yourself to grieve. Breakups can be extremely painful, whatever the circumstances. Even ending a toxic relationship can leave you feeling sad, angry, confused, and grieving the loss of shared dreams and commitments. Healing can take time, so go easy on yourself and turn to family and friends for support.
Don’t expect the narcissist to share your grief. Once the message sinks in that you will no longer be feeding their ego, the narcissist will likely soon move on to exploit someone else. They won’t feel loss or guilt, just that never-ending need for praise and admiration. This is no reflection on you, but rather an illustration of how very one-sided their relationships always are.
