This isn't a checklist that produces a verdict. It's a set of questions worth answering honestly, ideally out loud with a partner, before acting on curiosity about opening a relationship — because the reasons behind the decision predict the outcome more reliably than anything about the structure chosen.
The reason matters more than the structure
Two couples can choose the identical arrangement — say, an open relationship with the same rules — and have completely different experiences, because the reason behind the choice was different. Wanting it because it sounds genuinely exciting to both partners tends to go differently than wanting it because things have felt stagnant, or because one partner is hoping it will resolve a problem that has nothing to do with monogamy itself.
Questions worth answering honestly
- Is this something both partners actually want, or is one partner going along with it to avoid conflict, keep the relationship together, or avoid seeming insecure?
- Is the existing relationship already stable, or is there unresolved conflict, resentment, or a mismatched-libido situation that opening might be quietly expected to fix?
- What does each partner actually want out of it — more sexual variety, deeper emotional connection with others, a specific fantasy, something else? Vague, unaligned motivations tend to surface as conflict later.
- Can both partners tolerate some discomfort during the adjustment period without treating every hard feeling as proof the whole idea was a mistake?
Reasons that tend to work out better
None of this guarantees an outcome — no checklist can. But couples who go in for these reasons report meaningfully fewer regrets than couples who open up as a last resort for an existing problem.
Reasons that tend to work out worse
- "Maybe this will fix our sex life" — mismatched libido or a stale sex life is better addressed directly first; see our guide to mismatched sex drives.
- "I don't want to lose them, so I'll agree" — reluctant consent under pressure to keep the relationship tends to surface as resentment later, even when the reluctant partner didn't expect that of themselves.
- "We haven't actually talked about what this means" — going in with undefined expectations is one of the more common causes of the arrangement falling apart, not the non-monogamy itself.
Start with the conversation, not the plan
Before discussing logistics — apps, events, specific people — it's worth having a slower conversation about what each partner is hoping for and afraid of. Once there's real, mutual clarity on that, our guide to non-monogamy rules and agreements covers how couples typically structure the practical side.
Frequently asked questions
Is opening up a good way to fix relationship problems?
Generally no. Opening a relationship tends to work best when the existing relationship is already stable and both partners genuinely want it for its own sake — using it to paper over unresolved conflict, mismatched libidos, or resentment tends to add a new source of stress on top of the existing one instead of resolving it.
Does one partner being reluctant but going along with it ever work out?
Rarely well. Genuine, enthusiastic agreement from both partners is one of the stronger predictors of it going well — a partner who agrees mainly to avoid conflict or keep the relationship together is more likely to experience it as a loss than a gain, even if they don't say so upfront.
Do we need a therapist to have this conversation?
Not required, but a therapist experienced with non-monogamy specifically can help surface disagreements neither partner may realize they have before acting on them. See our guide to when to see a sex or couples therapist.
