Well, I like that quote and I am pretty sure I do not have BPD. When I say "like", I mean that I don't reject it, but instead find it an interesting position and would want to know what in particular someone who said it to me understood from it and what resonated for them. It would lead to a possibly enlightening conversation, in an ideal world.
On the surface this poemlette is not saying anything new, nothing we don't know already. Sure people become attached to things that they think will either give them answers or make them happy. Don't we all know this?
I think the first part can be true in many relationships, and as gotbushels pointed out, it can also apply to us "nons" - although in different ways.
I've been thinking a lot about distraction recently, as a matter of fact. For me, I ended up in my relationship with a pwBPD for a bunch of reasons: desire for connection, excitement about what felt like being truly seen, a huge desire for excitement spiced with a little danger and a lot of enigma, a desire to just give to another human, and yes, distraction.
Distraction from thinking about and figuring out myself. This gets really tiring!
Maybe the difference between my desire for distraction and that of my pwBPD was a matter of degree. In my view, he needed me to be as perfect as he decided (within a few days) I was and I was supposed to offer the comfort and peace and fun and solidity and stimulation and support that he could not give himself. He needed to be "distracted" from those lacks in himself. Another way to put it, is that he wanted to find those things in someone else and get them for himself by some kind of osmosis.
And I would say that I had some similar lacks and needs. The difference would be that mine were probably not as deep, that I had articulated many of them to myself already at different points in my life, and that I did not expect to "get" those things from him. I rather hoped that we would support each other in getting them for ourselves. There's nothing like a fellow traveler, for a while anyway, to join you on your quest to figure stuff out. (Or so I thought. I didn't count on ending up being expected to carry both suitcases while my fellow traveler took a break with someone else and then joined up again as if nothing had happened.)

So if I posted that quote on social media, I would not be saying that that is how I think. But rather, that that is one way to think about it. There can be a recognition of maybe a generalised human condition or a more personal recognition of ourselves somewhere in there. But if I view this quote with a sense of compassion, I see wisdom in it - but certainly not some kind of instruction on how to live or a sense of it being ok to live that way.
I can say that one of the reasons I hung on in the relationship (and there were a few different ones) was the knowledge that once I got him out of my system - once I stopped missing the individual entity that was him - I would be left with figuring myself out once again. All the reasons that I stayed for as long as I did are just the tip of the iceberg. Distraction is one of them. To look at what I needed to be distracted from in the first place is the work of a lifetime, it feels like.
