Use their survival method it's proven
You mean hurt the ones I supposedly love because I'm feeling out of control, even though I have constant chances to do something about it? In effect continually choosing to sabotage my own life? Demand I get what I so desperately need and want and then discard/denigrate it? You mean project and run? To not respect someone else's boundaries when they've had to go NC as a last resort/to heal from having been with me, because I abandoned them? Covering my shame with more shame? No thanks.
Whoa, songbook pretty much summed up the ol' borderline in one paragraph; extra ugly when condensed like that.
Although NC is not a survival method for a borderline, necessarily. Sure, if a borderline gets too close to someone they feel engulfed so they need to create distance, and once there's distance they feel abandoned so they come back, ye olde push/pull. And if they stay away it's because of shame, since a borderline never wants to lose an attachment, their lifeblood. Sure, they can get others, and usually maintain several concurrently, minimizes that pesky abandonment that is always an issue, but they don't like to let go of any of them, in fact they're convinced they'll always be left, even when they're doing the leaving. Crazy man.
Never say never. I was with mine the first time in 1987, thought we were exclusive but turns out I was one of many, same old sht, she got married and moved away, and I heard from her every few years, randomly, until she found me on Facebook in 2012, and off to the races we went again, because I thought she'd 'changed' (silly me), but alas, same old sht. Never say never, they don't like to let go all the way, it's a replaying of that earliest abandonment, or lack thereof, that created the disorder to begin with.
