I think this is a valid discussion because it is a situation that does come up on here and in reality. Historical threads on here discuss this very dynamic.
I personnaly do not see this type of situation as "poly" but, ironically, I have very lofty and idealistic views of what it should be even though I frundamentaly struggle with the concept on a continual basis.
I hope others weigh in on this .
