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.

Look at what you're really asking: can open relationships work? No. They're a fantasy that ignores human nature. You think jealousy and possessiveness are just social conditioning we can logic away. They're not. They're hardwired. When your partner sleeps with someone else, your brain releases cortisol. That's biology, not programming. Sure, maybe some people claim it works. But ask yourself: how many actually feel fulfilled, not just *accepting*? Most open relationships are just slow-motion breakups where people convince themselves it's liberating while slowly dying inside. The data on satisfaction tells the story—monogamy endures because it *works*. Openness sounds good until it's your person in someone else's bed. So what's your response? Can you name one thing that actually resolves the jealousy problem?
