I think under this framework, Aristotle might have suggested that, if the friendship falls apart, it was never perfect to begin with. It was based on utility or pleasure after all.
Then again, today’s environment is very complex. One thing I’ve noticed is that location is becoming a big issue. I’ve moved away from places where I’ve lived, studied, and found great friends who I shared struggle with. But now, if I don’t make an effort to stay connected to them through modern technology, like calling, texting, etc., these friendships sort of just “fade away.”
There seems to be no malice there. Everyone just moves on with their life, and because you’re not in close proximity, you just happen to see each other less often. But if I visit those friends, even once a year, the connection flares up again and it feels just the same.
So I think there’s another side to this, that is to maintain the perfect friendships you have, even across distances. Hope that adds some more color :)
