I appreciate this story.
While choice can be made - I think polyamory and monogamy are questions of wiring. Some people are poly and some are monog. Just like some are straight, some are bi, some are gay, and so on.
I find it more empowering to accept that its a wiring matter. And you can choose to be monogamous if you are wired to be poly - but I have yet to see that fully work - because it causes conflict just like someone gay choosing to be straight.
But in a society dominated by monogamous relationships - seeing poly as "other" or "alternative" and very much not the norm is just as unfortunate as the struggles of LGBTQA+ people for acceptance and normalization.
I am in a poly marriage that we are open about with my family - but not her family - because of their religious beliefs. And I think that's fairly indicative of where the view of "choice" rather than wiring causes unnecessary conflict.
Love is love.
