I can give you some general insights into how a narcissist might react when the victim finally walks away from the relationship.
When the victim decides to leave a relationship with a narcissist after prolonged efforts to make things work, the narcissist's response can vary depending on the individual and the specific circumstances. Here are some possible reactions:
Narcissistic Injury: The narcissist might feel a sense of wounded pride or ego due to the rejection. They may see it as a personal attack on their self-worth and superiority.
Abandonment Fear: Narcissists often have an intense fear of abandonment, so the victim leaving can trigger strong feelings of anxiety and insecurity.
Loss of Control: Narcissists like to maintain control over others and the relationship. When the victim leaves, they lose that control, leading to frustration and anger.
Idealization and Devaluation Cycle: In many narcissistic relationships, there is a pattern of idealization and devaluation. The narcissist may have previously idealized the victim, but when the victim leaves, they might switch to devaluation, deeming the victim unworthy or weak.
Manipulative Tactics: The narcissist might attempt to hoover the victim back into the relationship by using manipulative tactics, such as love bombing, promises to change, or guilt-tripping.
Lack of Empathy: Narcissists often struggle to empathize with others, so they may not fully understand the pain or hurt they caused the victim.
Blame-shifting: Instead of taking responsibility for the failed relationship, the narcissist might shift blame onto the victim or external circumstances.
Indifference: In some cases, if the victim's departure doesn't significantly impact the narcissist's ego or sense of control, they may act indifferently or dismiss the situation as if it doesn't affect them.
Regarding whether the narcissist always thought the victim was too weak to leave them, it can be a common trait in narcissists to perceive themselves as superior and believe they have power and control over others. However, not all narcissists will have the same level of insight or understanding of their victims. Some may genuinely be surprised when the victim finally leaves, while others might have been manipulating and using the victim's perceived weakness to keep them in the relationship.
It's important for the victim to prioritize their own well-being and safety, regardless of how the narcissist may react. Leaving a relationship with a narcissist can be difficult, and seeking support from friends, family, or professional counselors can be essential in the healing process.
