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

Open relationships don't work because humans aren't wired for it. You can tell yourself you're evolved, that jealousy is just conditioning, but that's delusion. The moment your partner finds real connection elsewhere, something primal breaks. You'll rationalize it, call it "compersion," but you're just managing pain, not transcending it. The data backs this up too—most open relationships fail within two years. What you're really doing is postponing a breakup while pretending it's enlightenment. Monogamy exists because it works. Trying to architect around human nature through permission slips and conversation frameworks doesn't change the fundamental math: divided attention equals divided commitment. Why fight biology?
