Yes, it is possible for a highly self-confident individual who deeply understands the dynamics of Cluster B personality disorders, including narcissism, to be manipulated and used by a narcissist. Even with a good understanding of these behaviors, certain factors can still make someone vulnerable to manipulation:
Empathy and compassion: Highly self-confident and empathetic individuals may find it challenging to comprehend the full extent of a narcissist's manipulative behavior, as they may be more inclined to give the benefit of the doubt or believe that the narcissist can change.
Emotional investment: If the self-confident individual has developed an emotional attachment or bond with the narcissist, it can be difficult to break away, even if they are aware of the manipulation.
Cognitive dissonance: Understanding the dynamics of narcissism does not always eliminate the emotional turmoil that can arise from being manipulated by someone close. Cognitive dissonance can lead individuals to rationalize or minimize the narcissist's negative behavior.
Isolation and gaslighting: Narcissists are skilled at isolating their targets from external support systems and using gaslighting techniques to make them doubt their perceptions and understanding of reality, even if they are well-informed about narcissistic behavior.
Personal vulnerabilities: Even confident individuals may have personal vulnerabilities or unresolved issues that narcissists can exploit for their gain.
Love and attachment: If the self-confident individual is in a close relationship with the narcissist, such as a romantic partnership or family connection, the emotional ties can be challenging to sever, even when they recognize the manipulative behavior.
It's important to remember that even if someone understands the dynamics of narcissism, being in a relationship with a narcissist can be emotionally damaging and detrimental to their well-being. Recognizing manipulation and setting boundaries is crucial, but seeking support from mental health professionals or support groups can also be helpful in navigating these challenging dynamics and finding ways to protect oneself.
