Whether a narcissist fully ends an affair they were having depends on various factors, including the personality and behavior of the individual in question.
Narcissists often have difficulty maintaining healthy relationships due to their self-centered and manipulative tendencies. They may engage in affairs for validation, attention, or a sense of power and control over others. Ending an affair may be challenging for a narcissist because they may struggle to empathize with their partner's feelings and fail to recognize the impact of their actions on others.
In some cases, a narcissist may end an affair if they no longer find it beneficial or if they fear exposure and potential consequences. However, they might also continue the affair if they believe they can keep it hidden or if they find it gratifying in some way.
It's essential to remember that not all individuals who engage in affairs are narcissists, and people's actions can vary based on their personal circumstances and choices. If you are dealing with a situation involving a narcissist or an affair, seeking advice from a qualified therapist or counselor can be helpful in understanding the complexities involved and finding a way forward.
