That could be the reason for all the restraining orders (my ex took out one on one of her former flings too).
But I think that HPD's really are more likely to be stalked/surveilled and yes, even threatened.
I do agree that they are more likely to be stalked due to their destructive behavior towards men and the resulted anger unleashed at them, but due to their compulsive lying I wouldn't be wholly surprised if they oftentimes fabricate and/or exaggerate the extent of their necessity of obtaining a restraining order. It certainly could be an attention-ploy (i.e, "Look at me! He STILL wants me!") in some instances.
You are dealing with women who lie pathologically to the men they are with -- yet at the same time do all they can to whip up jealousy in those men; women who slander men after break-up; women who use children to get back at exes, etc, etc. They also target attached men, then threaten to contact the man's wife or companion when it all goes south. Man says, "You'd better not, or I'll..." And bam! Restraining order.
In short, HPD behavior can make a stalker out of anyone. (Which does NOT excuse stalking behavior.)
In my case: a waiflike HPD ex sending constant guilt-giving, reproachful emails about how her life has ended since I left. How she is home every night, pining away, etc. Boo hoo. All the while she has been merrily dating other men as always! To put a stop to this lunacy - and to see the look on her face - I actually stood in front of her house to try and catch her coming home with a guy. Stalking behavior, plain and simple. I came to my senses, thank God, and went home. But never in my life had any woman induced me to behave like that!!
Read through this forum - you will read about so many men pushed to their limit. So don't let anything she does make you cross that line. An HPD is not worth becoming a stalker over.
I do see your position in how things could unravel so easily to the point of some people resorting to such tactics. I do not doubt other men have been pushed to their limits; I went through so much hell that it still sometimes comes back to haunt me in stray thoughts. And no, I would not dare cross that line. If someone doesn't want you, then there's really no point in convincing them otherwise. My theory on that is: I want to be someone's first and only choice, not a backup plan and certainly not with someone who doesn't willingly feel the same way as I do. In short, the best revenge is living well without them.
