I can offer some general insights about the behavior of narcissists.
When a narcissist goes quiet after their attempts to ruin your life have failed, it could mean several things:
Loss of interest: Narcissists often seek attention and control over others. If their efforts to manipulate or harm you were unsuccessful, they might lose interest and move on to another target they perceive as more vulnerable or responsive.
Focus on new sources of narcissistic supply: Narcissists constantly seek admiration and validation from others. If they find someone else who fulfills their need for attention, they may direct their efforts toward that person and shift their focus away from you.
Strategic withdrawal: Narcissists are skilled at manipulating situations to suit their needs. Going quiet could be a strategic move to confuse or elicit a reaction from you. They might hope that you'll reach out to them or try to re-engage, giving them another opportunity to exert control over you.
Temporary break: Narcissists' behaviors can be unpredictable and cyclical. They may go quiet for a period, only to reappear later when they believe the circumstances are more favorable for their manipulation.
It's important to understand that a narcissist's behavior is driven by their own emotional and psychological needs, and it may not necessarily reflect genuine forgetfulness or moving on. They may resurface later if they believe they can regain control or if they feel the need for attention again.
If you've experienced a toxic relationship with a narcissist, it's crucial to focus on your own healing and well-being. Surround yourself with supportive friends and seek professional help if needed. Establish healthy boundaries and avoid engaging with the narcissist if possible. Remember, recovering from the effects of a toxic relationship can take time, so be patient and compassionate with yourself as you move forward.
