A narcissist is unlikely to disclose negative information about themselves, especially something as serious as having an order against them from a previous victim. Narcissists are skilled manipulators and tend to present a carefully curated image to new "supply" (a term often used to refer to the next person they target for attention and validation). They want to appear charming, perfect, and faultless to win the admiration and trust of their new target.
Revealing that they have a restraining order or any other legal action against them would undermine their efforts to create a positive impression. They are more likely to hide such information or, if confronted, downplay it, deny it, or even blame the previous victim for their troubles, portraying themselves as the victim instead.
Remember that narcissists are highly focused on self-preservation and maintaining control over others. They will go to great lengths to protect their image and avoid anything that may jeopardize their ability to manipulate and exploit new targets. Therefore, it's essential for potential new partners or anyone involved with a person displaying narcissistic behavior to remain cautious and be aware of potential red flags.
