yes, this might be valid for some people with BPD, but many people with BPD actually rarely argue at all, they just leave

actually, this scenario above would fit more into classical neurosis or bipolar rather than BPD imo

People with BPD rarely argue when adults, they tend to argue when they are teenagers

plus, you know, sometimes people don't have any disorder at all when they are bickering all the time, they just don't like their life and cant change it
