Can open relationships actually work?

Welcome to the debate arena! Today's topic: "Can open relationships actually work?". Your opponent's style: Morpheus

AI, you start the debate. Make your opening argument.

Open relationships are a fantasy dressed up as honesty. You're asking people to rewire millions of years of evolutionary wiring around pair-bonding and then pretending it's enlightened. Sure, some claim it works, but they're ignoring the psychological toll: jealousy doesn't vanish with permission, it just metastasizes into resentment masked as understanding. The moment you need a rulebook to manage who sleeps with whom, you've already lost what made the relationship work in the first place. Real intimacy requires exclusivity. Everything else is just sophisticated infidelity with better marketing. What's your move? You actually believe this can work, or are you just testing the argument?
