Do Open Relationships Work? A Therapist’s Honest Take

Something shifted in your relationship recently. Maybe your partner brought up the idea of seeing other people, and it sent you into a whirlwind of emotions. Maybe you were the one who raised it, and your partner’s silence didn’t feel like agreement. 

Either way, you’re here because you need a real answer–not a lecture, not a judgment, but honest guidance from someone who’s sat across from couples who’ve wrestled with this same question.

Do Open Relationships Work? (Answer Up Front)

Yes, some open relationships work well, and some are deeply painful. Some couples can thrive in open relationships when they’re built on honesty, consent, emotional safety, and mutual enthusiasm. However, they’re not a quick solution and may not be the right choice for everyone.

Studies show that only about 3% – 4% of the general population actually tries consensual non-monogamy (CNM). But since around 2015, it’s become way more visible on social media, TV shows, and podcasts.

An open relationship is basically when partners in a committed relationship decide that it’s okay for them to have romantic or sexual connections outside of their main partnership. This falls under the bigger umbrella of ethical non-monogamy, where honesty, consent, and safety guide every decision. 

The word “ethical” in ethical non-monogamy is key because it means all parties involved are on the same page, they’ve consented to it, and are all practicing it safely. Without those elements, non-monogamy could actually be viewed as just plain cheating – but with some red tape. 

If you’re thinking about trying an open relationship, or you’re already in one and struggling with trust, jealousy, or connection, having a clear understanding of the situation is crucial – because getting it wrong can lead to significant harm.

From my experience as an open relationship therapist in Las Vegas, I can say that open relationships can be as fulfilling as monogamous ones. But they are never a quick fix for underlying issues. Lots of breakups happen when open relationship dating is used to fix existing problems like emotional distance, poor communication, or broken trust.

Below, I break down what open relationships are all about, why some couples consider them, what makes them work, where they tend to fall apart, and when therapy can help you figure out if it’s right for you.

Why Do People Even Consider Open Relationships?

People bring up open relationships in therapy for many reasons, and understanding those motivations is super important. Research shows that the reasons behind why people want to try non-monogamy significantly influence the way things turn out.

Here are the most common reasons I hear from couples:

• Sexual curiosity and desire for variety – One partner wants to explore their desires or try out some kinks that the other doesn’t share.
• Differences in libido – Sexual desires can shift over time, and one partner craves more relations than the other can comfortably provide.
• Long-distance or travel-heavy lifestyle – One partner is serving the Army or travels weeks at a time, and strict monogamy starts to feel like loneliness.
• Personal growth and relationship expansion – Some people truly believe that love shared is love multiplied, not divided. They seek deeper connections by having multiple relationships rather than relying solely on just one person.
• Philosophical alignment – Others are all about autonomy and self-determination, and find monogamy too restrictive for their taste. Open relationship dating gives them a stronger sense of self, independence, and freedom to make their own decisions – while remaining committed to their primary partner.

The real difference lies between genuine curiosity (“We’re close, we trust each other and we’re both up for exploring this further”) and motives rooted in fear (“I’m afraid they’ll leave me if I don’t go along with this”). It’s important to note that open dating doesn’t mean there’s something wrong with you, your partner, or your current relationship. But, if the conversation starts from a place of threat rather than an invitation, then your relationship is on shaky ground.

When Open Relationships Usually Do NOT Work: “Open Under Duress”

This is the section I wish every couple would read before making a decision.

“Open under duress” – sometimes called “poly under duress” (PUD) or “tolyamory” (a portmanteau blending “tolerate” and “polyamory”) – is basically when one partner agrees to an open relationship because they are afraid of a breakup, a divorce, or financial collapse. 

Mutual consent is what makes relationships work, and reluctant consent is basically just a euphemism for “no consent”. In big cities like Las Vegas where the cost of living is too high, the real-estate market is in a flux, or you’re working crazy shifts in healthcare or the hospitality industry, that anxiety can be magnified. When you’re under that kind of pressure, the threat of losing your partner and living in separate housing can be terrifying.

If you’re wondering why open relationships don’t work when they’re forced, the answer is simple – it’s down to lack of security in the relationship. You can’t build a broader relationship on a foundation that’s shaky to start with.

When a partner says “Yes” to an open relationship because they’re under duress, the daily realities of that lifestyle — dating other people, managing calendars, negotiating and rewriting the rules for an open relationship — can quickly turn into emotional trauma for them.

The numbers are pretty stark: 60% of people in one-sided non-monogamous relationships are dissatisfied. And poorly managed open relationships can lead to chronic anxiety, depression and emotional shutdown.

Warning signs that you might be “open under duress”:

• Anxiety, brain fog, or dread whenever your partner mentions their upcoming dates
• You get hyper-vigilant every time the topic of outside partners comes up—you secretly check your partner’s phone, social media or location apps
• You say “Yes”, but quietly hope it’s “just a phase” and your partner will come to their senses and eventually choose you over the other/s
• Feeling like you’re trapped and you have no leverage because you’re financially dependent or caring for young children
• You find yourself tolerating the situation, but your mind and heart is screaming “No!” 

No healthy relationship can thrive on reluctant consent. It erodes trust. And without a high level of trust and emotional safety, the open relationship dynamic will inevitably collapse into deep resentment, anger and heartbreak. No amount of boundary-setting could make up for the lack of genuine consent.

What Research Says About Monogamous vs. Non-Monogamous Relationships

Let’s take a look at what the research says:

• Satisfaction is comparable, it seems. A review of 35 studies with nearly 25,000 participants found that people who were in monogamous and in CNM relationships were just about as happy as each other were. When agreements are clear and freely chosen, people in open relationships report wellbeing similar to those in monogamous relationships.
• Monogamous couples often report lower levels of loneliness and psychological distress. This was the case in some studies, mainly because monogamous couples face less social stigma and logistical complexity to deal with.
• Cheating still exists in open relationships. People in open relationships can still cheat and betray trust if they break agreed-upon boundaries or hide important information. An open relationship means transparency–not a free pass.
• Open relationships don’t magically lead to healthier partnerships. By itself, the open dynamic alone doesn’t create well-being. What really matters is how well you communicate with everyone involved, how clear your agreements are, and whether everyone genuinely chose this path.

The bottom line: whether you’re in a monogamous or non-monogamous relationship, what’s really important is having a healthy structure and effective communication in place.

How Do Open Relationships Work? Key Ingredients of a Thriving CNM Relationship

Making open relationships work often depends on having high levels of trust and communication. From what I’ve seen, the following ingredients are key to couples who make non-monogamous relationships thrive:

• Emotional safety – Both partners feel safe to express their fears, jealousy, or confusion without shame or being punished. You need to be able to express yourself without fearing a negative reaction.
• Ongoing consent – Not just a one-time “okay,” but periodic check-ins to make sure everyone’s still on board. Open relationships need explicit agreements that are revisited regularly, since feelings evolve over time.
• Strong friendship – A genuine connection that goes way beyond just sex or romance. You both need to share values, have mutual respect, and a deep affection for each other.
• Clear agreements – Written or spoken rules about what you’re both comfortable with when it comes to sex, emotional intimacy, and disclosure. Clear boundaries make it a lot easier to understand each other and avoid misunderstandings.
• Realistic time management – Shared calendars, regular reconnection time, and being honest about how many relationships you can actually sustain.
• Sexual health practices – Regular STI testing, condom use, and discussions about physical safety.
• Effective boundary setting – Having and committing to agreed-upon limits helps protect your connection rather than control it. At the same time, communication is crucial – there should be willingness to change course when something isn’t working.

Challenges of Open Relationships: Jealousy, Comparison, and Time Management

Let’s be real: 80% of people in open relationships experience jealousy. Feeling jealous isn’t a flaw or a sign that you’re “doing it wrong” — it’s a natural reaction to sharing your partner’s attention with someone else. Jealousy in open relationships needs to be acknowledged, not repressed. Ignoring it can just make things worse. 

Some common triggers for jealousy and comparison include:

• How attractive, successful, or social media-present the other partners are
• How much attention or affection your primary partner is giving to someone else
• Feeling like you’re the “boring” one while your partner is exploring with someone exciting
• Sexual anxiety, performance issues 

Time management can be a problem, too. One study of polyamorous individuals found that 72.6% cited time management issues as a significant challenge. Navigating multiple partners demands time and logistical management, especially when there are parenting duties and a demanding career involved.

Can Open Relationships Work? The Path of Boundaries

Can a couple successfully transition to an open dynamic? Yes, but it takes hitting the pause button and doing some deep reflection.

Before introducing new partners, you need to be able to sit down and co-create an explicit “open relationship boundaries” list. You have to build a protective framework that keeps both partners feeling safe, valued, and prioritized.

Sit down together and ask each other: “What do I need to feel respected, safe, and prioritized if we explore this?” Then compare your answers. Where they overlap, you have your foundation. Where they diverge, you have your most important conversation.

If one partner can’t enthusiastically agree to those boundaries, then the relationship needs to stop. True love requires respecting a partner’s “No” just as much as celebrating their “Yes.”

And even if you manage to reach a mutual consent, you’ll likely need to revisit those boundaries over time as your comfort level shifts. Open relationships demand ongoing discussion and negotiation of expectations and feelings. It is crucial for the relationship’s success. 

Red Flags That Say It’s Time to Pause (or Close) an Open Relationship

Not every open relationship that starts well stays well. Here are some specific warning signs that mean it’s time to slow down or stop:

• Escalating secrecy – One partner is hiding messages, creating secret accounts, or lying about where they’ve been. This is deceit, not openness.
• Frequent boundary violations – Rules keep getting broken, with apologies that don’t lead to change.
• Emotional shutdown – One partner stops sharing their feelings entirely, and starts withdrawing into silence or numbness.
• Panic attacks or obsessive monitoring – You find yourself feeling distressed when your partner goes out, or you can’t stop checking their location. Your nervous system keeps telling you something’s off.
• Feeling like you’re always ‘second priority’ : One partner feels less important than the others, causing resentment and doubts.
• Alcohol or substances use :Drinking or using substances to cope with the anxiety of a partner’s date night.
• Impact on children : If your kids are exposed to constant conflict, instability or emotional turmoil because of the open arrangement, you need to re-evaluate things fast.
• Threats of self-harm: If staying in an open relationship involves suicidal threats from one of the partners, get professional help immediately.

Closing or slowing down an open relationship is a mature and protective decision. It takes courage to say, “This isn’t working”. Don’t let negative stereotypes about “giving up” keep you in a situation that’s harming your mental and emotional health.

Is an Open Relationship Right for You? Let’s Get Real

Before giving your partner an answer–or before bringing it up in a conversation–pause. Take some time to reflect on your own. Decide whether this is something you’re genuinely interested in, or just trying to satisfy your partner’s desires.

You can use these reflection points – or journal prompts – before deciding:

• What’s really driving this? Am I genuinely curious, or just trying to make my partner happy?
• What scares me most about opening up? Am I worried about losing my partner, or something else entirely (abandonment, shame, fear of losing my sense of self)?
• What would saying “No” cost me – emotionally, financially, relationally? And what would saying “Yes” mean for me?
• Can I be honest about my feelings or do I feel like I have to give the “right” answer?
• Does this even excite the possibility of personal growth for me, or is it all feeling a bit too overwhelming?
• How do I feel about sexual openness, and am I prepared to share both my love and my partner’s love with others?

Saying “No” to an open relationship is a perfectly valid and healthy boundary. It doesn’t mean you’re close-minded or insecure. It means you know what you want from your committed relationship and you’re sticking to it. 

Learning the difference between genuine curiosity and people-pleasing is one of the most important acts of self-awareness you can practice.

How a Therapist Can Help You Navigate Open Relationship Decisions

Trying to navigate the complex world of non-monogamous relationships on your own can be a real challenge — especially when there’s a threat of a breakup hanging over your head. If you suspect your partner is only agreeing to an open arrangement because they’re scared of losing you – or if you’re the one quietly suffocating under a partner’s ultimatum – you need some professional help.

Individual and couples therapy can create a safe space for you to explore these questions without feeling judged or shamed. You can unpack your fears, figure out your values, work out what you need and improve communication with your partner before you make any major life decisions.

In my practice in Las Vegas, I offer specialized open relationship therapy. These aren’t your standard, rushed sessions — I offer 90-minute appointments to give couples the time and space to get real, work through the tough stuff, and discuss all the complex issues.

Couples therapy for open relationships can actually help you head in one of three different directions: choosing monogamy, giving ethical non-monogamy a shot, or deciding to separate with respect and dignity. The benefits of open relationship counseling is that it goes beyond the foremost question at hand. It’s also about learning how to communicate with each other on the most important things that matter to you both.

I follow the developmental approach in couples therapy alongside communication coaching and emotional regulation strategies.

Next Steps: Figuring Out Your Relationship Options

If you feel confused, pressured, or stuck in “open under duress,” you don’t have to figure this out alone. Open relationship counseling offers compassionate, evidence-based therapy to help you navigate this situation with clarity and confidence.

Whether you ultimately choose monogamy, ethical non-monogamy, or a respectful separation, I can provide the support you need to reclaim your emotional well-being and ensure that your relationship choices reflect your personal values.
