I can provide some general insights into this kind of behavior.
When dealing with a narcissist, their silence after their attempts at ruining your life failed could mean a few different things:
They are focusing their attention elsewhere: Narcissists tend to be self-centered and may lose interest in someone once they feel they can no longer manipulate or control them.
They are planning their next move: Narcissists can be calculating and may be taking time to strategize new ways to cause trouble or get what they want.
They are trying to provoke a reaction: Silence can be a tactic used by narcissists to provoke a response from you. They may want to see if you'll chase after them or try to reconnect.
They have genuinely moved on: In some cases, a narcissist may genuinely lose interest and move on to a new target.
It's important to remember that narcissistic behavior is complex, and individuals can vary significantly in their actions and motivations. Their silence should not be taken as a signal of them "forgetting" you, but rather as a potential shift in their focus or tactics.
Regardless of their intentions, it's essential to prioritize your own well-being and focus on healing and building a healthy life for yourself. If you've experienced the negative effects of a narcissistic relationship, consider seeking support from friends, family, or a professional counselor who can help you navigate the aftermath and build resilience.
