http://Not trying to pick your post apart, but if contact is made to see if "the hook is still set" (selfishness and unhealthy validation), isn't that much different than a recycle attempt?
I think it is but I am no expert, that is for sure.
I was always dumbfounded and disturbed by the contacts. I believe they were to see if the hook was still set... .but will never be sure?
My expwBPD had run off with new supply and was living with him. Continued to lie to me that she had been cheating.
I got a 4x drive-by once where I live and then (incoming, help!) a pull-in... .to chat? -bizarre-
I've gotten staged "accidental run-in" in grocery-store parking lot ( ambush)

I've also gotten the ole' "pull up next to me at a traffic light at night, put on the dome light and strike a pose" thing? Super bizarre. Think I was supposed to break down and call her or something... .again ... .not sure... .who knows? Was that a recycle attempt? It's hard to know when you are dealing wit a whacky, crazy BPD.
I think all of her many contacts were for some kind of self-validation, but I will never really know.
Arc... .your contact seems like the same kind of thing. She used a ridiculous excuse to make contact (where she can, in her mind, pass off the reason for contact on you, [he was YOUR friend after all]). My guess would be that she is just on a fishing expedition for her own selfish needs. Nothing more. I believe you stayed NC, right? If so, good move my friend.
