I dated a girl with (I would guess) BPD for a couple months, and it was either fine (most of the time) or a hellish nightmare. I gave up when she shouted at me for two hours, started physically shoving me, then threatened to call the cops on me because I spent an hour talking to her (chill male) roommate after she had gone to bed. I ended up suffering fairly severe anxiety attacks for at least another month or two, and felt tremendous guilt and regret that I couldn't help her, as well as anger at her behavior.
She was otherwise an apparently successful masters student who I'm sure can hold down a job for years at a time. But taking completely senseless abuse just isn't worth it for the vast majority of potential partners, even if the BPD person has many redeeming qualities and can't control their outbursts.
I wish her (and everyone in a similar situation) all the best, but I am too emotionally sensitive and empathetic to be able to deal with that for the long term without going nuts myself.
