Idk, my polycule is complicated enough to need a graph for explanation and we’re having a wonderful time

Granted I keep my partners separate, as in they don’t date each other, so if a breakup happens it doesn’t cause a whole mess

It can be messy and it can be complicated, but it really doesn't have to be.

I know and bunch of people including myself who are very adult about their (romantic) long-term relationships. Those people tend to work hard in themselves and their relationships, especially in the first few years though.
