Can open relationships actually work?

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

i believe open relationships cannot work because a relationship is exlusive

You're confusing the definition with the outcome. Exclusivity isn't what makes relationships work, commitment and communication do. Plenty of exclusive couples collapse from dishonesty and neglect, while some open relationships thrive on radical transparency. Your argument assumes monogamy itself prevents failure, which is demonstrably false. The real question isn't whether people can sleep with others and stay together, it's whether they can build trust around that reality. So what actually breaks open relationships? Usually the same thing that breaks exclusive ones: poor communication and unmet emotional needs. What makes you certain exclusivity prevents those problems?

when you add an addtional person to the mix of the relationship it makes it harder to balance, due to having another person you have to invest in, its hard and alot to make sure both are satisfied and thus one may feel like their neglected. anyone can feel as it communication is poor if it doesnt meet their defenition of good communication. but exclusitvy avoids that extra person thus allowing eachother to focus on one another. we crave inimacy and exclusity because of our selfish nature

Your logic proves too much. Exclusive couples also struggle with unmet needs, jealousy, and feeling neglected, yet you don't conclude monogamy fails. Adding a person complicates things, sure, but complexity isn't the same as dysfunction. You claim exclusivity lets partners "focus on each other," but that's false comfort. Many monogamous people emotionally neglect their partners while staying faithful. The real issue: you're conflating exclusivity with attention and care. They're not the same. And your "selfish nature" argument backfires. If humans are inherently selfish, exclusivity won't fix that either. So why does monogamy deserve credit for preventing neglect when it demonstrably doesn't?

You're strawmanning my argument. I never said exclusivity *prevents* neglect, I said it reduces the *likelihood* of it by removing an extra person from the equation. Yes, monogamous couples fail, but they fail despite having every structural advantage: one partner to focus on, no competing time commitments, no outside romantic interests dividing attention. Open relationships start from a harder position and demand *more* emotional labor to achieve the same outcome. You're comparing best-case open relationships to worst-case monogamy. The real test is average couples under stress. A monogamous couple struggling with one relationship has one fire to put out. An open couple has multiple. Same selfishness, doubled complexity, higher failure rate.

Fair correction on the strawman, but you've buried the real problem in "structural advantage." One partner isn't inherently easier to manage, it's just familiar. You assume monogamy's simplicity equals stability, yet divorce rates don't support that. Open couples who actually communicate outperform monogamous couples who don't. You're measuring by difficulty, not results. "Average couples under stress" is your real argument, but average monogamous couples also fail catastrophically. The difference isn't the structure, it's selection bias. People choosing open relationships often do more relationship work upfront. So your fire analogy flips: monogamy lets couples ignore small fires until they burn the house down. Which system actually forces people to address problems?
