Narcissists can be unpredictable and their behavior may not always follow a logical pattern. However, there are several potential reasons why a narcissist might leave their "best" supply, especially if it is the person they married:
Need for Constant Validation: Narcissists crave constant admiration, validation, and attention from others. Over time, they may become dissatisfied with the level of adoration they receive from their spouse, and they might seek out new sources of admiration and attention.
Idealization and Devaluation: In many cases, narcissists engage in a cycle of idealization and devaluation in their relationships. At the beginning of the relationship, they may idealize their partner, putting them on a pedestal and making them feel like they are the most important person in the world. However, as the relationship progresses and the initial excitement wears off, the narcissist may begin to devalue their partner, finding fault in them and treating them poorly.
Boredom and Entitlement: Narcissists often get bored easily and have a strong sense of entitlement. They may feel that they deserve something better or more exciting and might leave their spouse in search of new experiences or new sources of validation.
Lack of Empathy: Narcissists typically lack empathy and have difficulty understanding and considering the feelings of others. They may not truly care about the emotional well-being of their partner and might be willing to discard them without much concern for the emotional impact it has on them.
Control and Power: Some narcissists thrive on power and control in their relationships. If they feel that they are losing control or dominance over their spouse, they may choose to leave the relationship as a way to reassert their sense of power.
Infidelity: Narcissists may engage in extramarital affairs to satisfy their need for attention and validation. This can lead to the breakdown of the marriage and the eventual departure of the narcissist from their spouse.
Fear of Intimacy and Vulnerability: Narcissists often have deep-seated fears of intimacy and vulnerability. As the emotional connection in the marriage deepens, they may feel overwhelmed by their own emotions and choose to distance themselves from their partner to avoid these uncomfortable feelings.
It's important to note that not all narcissists will follow the same patterns, and each individual's behavior can vary. Additionally, relationships involving narcissists can be complex and emotionally challenging, and seeking support from a therapist or counselor can be beneficial for those affected by such dynamics.
