I am familiar with the symptoms. I still think you deal with an actual narcissist, not with someone with BPD. The symptoms may have some overlap, but it's different.
For example, where in that article do you see that people with BPD can be so straight up delusional that they think they "own the town"? Notice that the words "lie" or "lying" do not even appear in the article.
In my experience, presenting a BPD-afflicted person with definitive truth is actually calming them down, because it disperses the worries and fears they have about things that could be (however unlikely).
Again, I don't mean to belittle your experience. What you're going through sucks, regardless of what disorder your wife has.
