Fallon the chronic gremlinIf you're a borderline and you need to get a toxic FP out of your life, just ask them their opinions about social issues and eventually you'll find a bigotry that just shatters your positive opinion of them.
At least that would work for me, lol #BPD
Just weaponize your own split response.
Live in Split City for a minute, and then you're done, split on that asshole forever and they are no longer your concern. No more of your emotional health depending entirely on a complete tool.
I've found that in my 30s, I don't have the BPD experience of a Favorite Person anymore. I'm so glad I've at least recovered that much from my mental illness. Having your emotional state be entirely dependent on Some Douche is TERRIBLE. #BPD
