She specifically said "It's interesting you would mention narcissism because I was diagnosed twice with a similar condition to NPD called Borderline Personality Disorder" and I said "You don't have BPD, but I promise that if you ever decide you don't like me anymore, I won't say it's because you have a personality disorder".
I don't trust "clinical diagnoses" from Big Pharma and more than from SS.
I can pretty much promise you that you aren't dating a full blown BPD
no matter how "alpha" you are or how strong your "frame" is, you cannot "cure" a personality disorder with your alphaness.
BPD's cannot hold a job, are unstable, can't keep friends, cut themselves, steal, cheat, lie, rage, fall into depression, have eating disorders, hear voices in their heads, have panic attacks, go to the hospital in fits of hypochondria, think the devil is following them around etc etc etc
Their core identity is VICTIM. so they will constantly victimize themselves and tell you about how everyone is so mean to them. EVEN IF they are "happy" with you, they will constantly be at war with SOMEONE. They have to be, BPD's don't do happy relationships, their default setting is chaos and drama, they HATE being happy. If they meet some "super alpha" dude who is the man of their dreams, after a while the disorder overrides their brain and they compulsively ruin it. You can keep them chasing you for a while, but not permanently.
They will inexplicably **** it up with you and a week later be dating a broke, ugly Beta and you will be left thinking wtf.
Yeah i can see how a really alpha dude may last longer and may even slightly improve the BPD's behaviour by being a strong role model, hell i'll even conceed a POSSIBILITY that she won't aim any of her unhealthy behaviours at him.
But in the end the biggest alpha in the world is going to see his BPD doing and saying bizzare **** and eventually say "well, i'm outta here then" and just leave.
The sweetheart who you have fully under control is NOT BPD from your description, not even close.
They are untamable, they are way too far gone for that, the damage was done to them decades before you met them and isn't fixable.
I repeat
they are UNTAMABLE
