I can offer some insights into the potential dynamics at play in the situation you described.
It's essential to be cautious when interpreting changes in behavior, especially when dealing with someone who exhibits traits of narcissism. When a covert narcissist starts treating you better or stops engaging in harmful behaviors like giving silent treatments after you send sexual texts, it's important to analyze this situation carefully.
Narcissistic Supply: Covert narcissists still crave attention and validation, but they may seek it in more subtle ways than overt narcissists. Sending sexual texts might have provided a form of narcissistic supply, boosting their ego and making them feel desired.
Manipulation: Narcissists are skilled manipulators. They may use positive reinforcement, such as improved treatment, to encourage behaviors that serve their interests. By responding positively to your sexual texts, they may aim to reinforce and encourage more of such behavior from you.
Emotional Manipulation: Narcissists may withhold affection or use silent treatments as a way to control and manipulate their partners emotionally. Stopping these negative behaviors after receiving sexual texts could indicate they found a new way to control you emotionally.
Idealization and Devaluation: Narcissists tend to cycle through idealization and devaluation phases in their relationships. During idealization, they shower their partner with attention and affection to gain their trust. Afterward, they may devalue their partner and use tactics like silent treatments. Your partner's improved behavior might be a part of this cycle, and the dynamics might change again.
Boundary Violation: Sharing intimate content, such as sexual texts, can be a boundary violation if it is not consensual or doesn't align with your comfort level. Be cautious about engaging in any behavior that you're not entirely comfortable with, as it can be used against you.
It's crucial to remember that genuine change in a narcissistic individual is rare, as their behaviors are deeply ingrained in their personality disorder. If you suspect your partner is a covert narcissist, consider seeking support from a therapist or counselor who can help you navigate the relationship dynamics and make decisions that are best for your well-being. Setting healthy boundaries and prioritizing your emotional safety is essential in any relationship.
