Will a narcissist keep cheating on spouse if they do it once?

While not all narcissists will continue cheating after one incident, many may struggle with impulse control and a lack of empathy, which can lead to repeated infidelity. Their need for validation and admiration often drives them to seek out new partners, making it more likely that they will cheat again. Additionally, if they feel they can avoid consequences, they may not see a reason to change their behavior. Ultimately, individual behavior can vary widely based on personal circumstances and motivations.
