No such thing as polyamorous relationship?
I knew that would get your attention... ;) Don't worry, I'm not here to attack anyone! :)
I've just been sitting here reading & pondering, and some things occur to me...
I believe that it's the PEOPLE, not the relationships, that are monogamous or polyamorous. Relationships themselves are exclusive or non-exclusive.
If a monogamous person falls head over heals in love with a polyamorous person, and the poly person says "look, I love you too, but I'm not going to give up my lifestyle to be with you" then that monogamous person may choose to enter a non-exclusive relationship. This does not make that person polyamorous.
If a polyamorous person falls head over heals with a monogamous person, and the monogamous person says "look, I love you, but I can't be with you if you're going to see other people" then the poly person may agree to enter an exclusive relationship. This does not make that person monogamous.
They're both between a poly person and a mono person, so how do you call one relationship polyamorous and the other monogamous? It makes more sense to me to call one non-exclusive and the other exclusive.
Putting aside the obvious fact that neither of these relationships is likely to last forever, neither is a total write-off. I've always been polyamorous, but I've been in both exclusive and non-exclusive relationships, depending on where I was at the time. Both types have been successful, meaning we had fun while they lasted and things ended on positive terms.
It seems that this approach side-steps the whole business of "our relationship is polyamorous because of this or that feature, but yours isn't because it lacks this or that feature."
If a relationship can be said to be polyamorous, I think it's because BOTH PEOPLE in the relationship are polyamorous, whether or not they're currently in love with any other people or having random sex with strangers. But I believe it's the presence of two polyamorous people in a relationship that makes it polyamorous, and not their relationships with other people.
I do not need a label to define me. Labels are sticky and I hate the glue they leave behind.
