Was convinced into one by (what seemed like at the time) a fairly cool lady who was married, husband had his own couple girlfriends, was an open marriage all above board, I thought I’d broaden my horizons and see how it went. She had no one outside the marriage and it quickly became VERY apparent why, hoo boy was that woman a horrible horrible person when she wasn’t pretending to be likeable. Never gonna mess around with that again, monogamy or nothing for me.
