Narcissists often have a deep-seated need for validation, admiration, and control over others. When a narcissist's relationship with their partner ends and they see their ex with someone else, it can trigger several negative emotions and reactions:
Ego bruising: Narcissists have fragile self-esteem and an inflated sense of self-importance. Seeing their ex-partner with someone else may be perceived as a threat to their self-image and ego. It can be difficult for them to accept that their ex has moved on and is finding happiness with another person, which can result in jealousy and resentment.
Loss of control: Narcissists like to be in control of their relationships and those around them. When their ex starts dating someone new, they lose that control, and this can be unsettling for them. They may feel a sense of powerlessness and an inability to manipulate their ex's feelings and decisions anymore.
Fear of being replaced: Narcissists often view relationships as transactions, where they expect to receive constant admiration and attention. The idea of being replaced by someone else can evoke feelings of insecurity and fear of abandonment.
Lack of narcissistic supply: Narcissists thrive on attention, admiration, and validation from others. When their ex-partner moves on and finds someone else, the narcissist loses a primary source of narcissistic supply. This can lead to a feeling of emptiness and the need to seek alternative sources of validation.
Sense of entitlement: Narcissists tend to believe they are special and deserving of special treatment. When they see their ex-partner with someone else, they might feel that their ex owes them loyalty or should still prioritize their feelings, which is a manifestation of their sense of entitlement.
Need for superiority: Narcissists often see themselves as superior to others and may feel threatened when they perceive their ex-partner's new partner as being better or more successful in some way. This can lead to envy and resentment.
It's important to note that not all ex-partners of narcissists will experience the same level of animosity or jealousy. Narcissism exists on a spectrum, and individuals with narcissistic tendencies may exhibit varying degrees of these behaviors. Additionally, some individuals may grow and change over time, leading to different reactions and coping mechanisms post-breakup.
