Nah, by the time they're old enough to date it's too late. Too much neurological development, too many life experiences that have validated the behavior. I think the only possible cure for BPD/narcissistic/etc. girls is
>early identification of problematic ideation and behavior>permanent removal from home environment (mommy and daddy usually plant the seeds of this shit, even past the genetic aspects)>exposure to a very knowledgeable and very mean psychotherapist >shrink needs to be able to identify problem ideation ("well he just ran away because he can't handle a strong woman, and he's a gaslighter, and-")>shrink then needs to be able to verbally bash that shit away ("no, he left you because you're a mouthy, nasty bitch with attitude problems, and I'm not saying that because of a personal problem with you, I'm saying that because you're a mouthy, nasty bitch with attitude problems")>girl then needs to be placed into a normal home with parents that have some kind of psych training to keep her on the straight and narrow Of course, that shit is insane and not possible or practical. So just do what
>>33360613 says and use her for however long. Some poor bastard will scoop her up later in life and one or both of them will wind up in prison.
