My knowledge of BPD is reading a few articles online to better understand it, but Google doesn't make you an expert

So I've been dating this girl for about 4 months now and I'm really happy with her. Unfortunately we live kinda far away so we see each other an evening, maybe two a week. We are still in the "infatuation" stage so it's mostly lovey dovey stuff at the moment, not that there is anything wrong with that. Our first few dates were pretty much very amusing job interviews so we learned a lot about each other, but not crazy in depth. I intend on a serious relationship, however I would like tips, advice, anything on dating someone with BPD. All feedback helps!
