personally I think "emotional monogamy" should just be called "monoamory", because "amory" is emotional.
I've always wondered why be put monogamy vs polyamory, when I feel they're on different scales. Monogamy means one spouse, in my opinion it means you stay with that one person and don't cheat on them regardless on whether you love them or not. I think you can be monoamorous in a poly relationship or polyamorous in a mono relationship. To me "monogamous" applies to the relationship, what applies to the people is "monoamorous".
Utlimately though I think what matters is knowing what you mean, not making sure we use a word everyone agrees with or that everyone uses the word we want them to use. Really, I prefer just shoertening it to "mono" and "poly" because that "solves" the problem or whether it's followed with "amory/amorous" (love) or "gamy/gamous" (partner).
