I'm downvoting you because it's ridiculous to say that monogamy is purely a social construct. It genuinely matters to some people, even if they're okay with polygamy as a general concept. There is nothing wrong with consensual open relationships, and we'd all be better off if the social stigma around them went away, but consensual is the key word. It's not okay to promise someone monogamy and then break your word behind their back.

Do not assume that the way you feel about something is the one true correct way and anyone who disagrees has been brainwashed by The Man.
