Uh, I don’t really see what this post has to do with mono vs poly. This just kinda comes off as you putting down poly relationships with no prompting.

It’s a different relationship structure. Works for some, not others. You don’t need to do it like that if you don’t want to. But for some of us it feels a lot more natural.

And you do need to be careful with anecdotes, yeah. Because it could all be from just randomly this being specifically the case with your friends, to some other reasons correlated with, but not caused by, poly itself (like people doing poly for the wrong reason) etc. Personally I do not see a relationship between mono and poly to struggles, I see a relationship between personal struggles and relationship struggles. And there’s no shortage of mono relationships imploding either.
