It is challenging to speculate on individual situations without knowing the full context and details. However, I can offer some general insights that might shed light on why your wife, who you suspect is a narcissist, has not filed for divorce despite being in a new relationship:
Fear of abandonment: Narcissists often have a deep fear of abandonment and may avoid initiating a divorce because they fear losing the sense of control and validation they have over their current relationship and you as their spouse.
Desire for control: Narcissists thrive on controlling others and maintaining power over them. By not filing for divorce, they may feel like they can continue to manipulate or exert control over you emotionally or financially.
Fear of negative consequences: Divorce can be a complex and emotionally charged process, and narcissists may be hesitant to face potential consequences, such as dividing assets, child custody arrangements, or the social stigma associated with divorce.
Ensuring a backup plan: Some narcissists like to keep multiple sources of supply (emotional validation), and having a backup relationship might make them feel more secure in case the new relationship doesn't work out as expected.
Psychological manipulation: Narcissists are skilled at playing mind games and manipulating situations to suit their needs. By not filing for divorce, they might be trying to keep you in a state of confusion or vulnerability, making it easier for them to control you.
Delaying the inevitable: Sometimes, people, including narcissists, might postpone difficult decisions like divorce because they are not yet ready to fully confront the emotional consequences or fully let go of the current situation.
Remember that narcissistic behavior can vary greatly among individuals, and the reasons for their actions may not always be immediately apparent. It's essential to prioritize your well-being and seek support from friends, family, or a therapist to navigate through the challenges you are facing. If you are considering divorce, consult with a legal professional to understand your rights and options.
