Is it BPD or is she just a jerk?
Probably a little bit of both.
I think Thunderstruck has it correct in that a pwBPD often feels out of control. It's where you'll see certain [BPD] behaviors of trying to regulate that - it's the catch 22 of the disorder. Intense feelings + the lack of skills to regulate emotions = tough stuff to deal with it.
I think she's exhibiting this kind of "puffing out the chest" because she lost control of the situation (court said she had to take SD to the ballet performance even though she did not want to). This helps her equalize those feelings by dictating to you "how it's going to be". It really, truly makes sense to her to not make it any easier on you.
I think this came from one of her domestic violence websites. She is back to claiming they have this long history of DV again. I think it is to benefit her new BF turned husband that she has known for 7 months.
Probably.
It's part of her coping mechanisms to deal with the loss of the relationship that she carrys with her (he didn't really leave her, she left him because he was abusive). It's the Karpmen's Drama triangle at play (for all of you). It's all part of lacking a skill set to function in relationships. In life.
She's human too - and just like all of us - can certainly be a jerk. Making you drive an hour out of your way "just because" sounds kinda jerky to me.
It's not taking it personal that's the key to our survival.
