When Just One Love Doesn’t Make Sense: Ethical Non-Monogamy

For some people, the idea of having one romantic or sexual partner for life feels natural. For others, it can feel like trying to squeeze into a box that never quite fit.

I was first introduced to the idea of non-monogamy through a daytime movie, Paint Your Wagon with Clint Eastwood. I was 12, it was the school holidays, and I’d spent the day at my mum’s work, with little to do but flick through the five basic TV channels in an empty boardroom. In the film, the female lead is faced with choosing between two men. But she refuses. She loves both of them. The story unfolds with the three of them living together in harmony. No jealousy, no rivalry, at least not in the way my 12 year old eyes understood it. And I remember thinking, “Well, why not?”

Years later, I still found myself sitting with that same question. The idea of multiple intimate relationships never quite left me. And then eventually, I discovered ethical non-monogamy.

What is Ethical Non-Monogamy? 

Ethical non-monogamy (ENM) is an umbrella term for relationship styles where people have more than one romantic or sexual connection, with the knowledge and agreement of everyone involved.

It’s important to distinguish this from secrecy or cheating. The word ‘ethical’ really matters. ENM is built on honesty, consent, and communication, even when things feel complex or emotionally layered.

People are drawn to ENM for many reasons. Some experience love as something that can be expansive rather than exclusive. Others feel that different relationships meet different needs, such as emotional support, intellectual connection, physical intimacy, or shared adventure. And for some, monogamy has simply never felt like a natural fit, even if they have tried it in good faith.

If you have ever thought, “I care deeply about my partner, but I don’t think one person is meant to meet every need I have”, you are not alone in that. ENM offers a framework for exploring relationships outside the traditional script, without assuming that love has to be limited to one person at a time.

Common Myths 

There are a lot of assumptions about ENM, and many of them don’t reflect how people actually practice it.

Myth: ENM is about avoiding commitment

Reality: There’s a common assumption that ENM is chaotic, unstructured, or a way of avoiding commitment. In reality, many ENM relationships involve a high level of communication, consent, boundaries, and emotional awareness. It’s not a free for all. It is more like co-creating a relationship structure that fits the people in it.

Myth: ENM is just about sex

Reality: Some people are open to sexual connections outside their relationship, while others focus on multiple emotional relationships. In fact, some ENM relationships don’t involve sex at all. For example, someone who is asexual may (but not always) choose not to have sexual relationships. ENM can look very different depending on the people involved.

Myth: You cannot love as deeply if you have multiple partners

Reality: If you ask a parent whether their love for their first child diminished after having a second, the answer is usually no. One of the biggest myths is that love is finite. In practice, ENM often requires people to be more intentional about how they spend time together and how they show care.

Myth: You cannot be ENM if you get jealous

Reality: People in ENM relationships can definitely experience jealousy! Insecurity, fear of loss, and comparison can show up in both monogamous and ENM relationships (we explore insecurities in relationships here). The difference is not whether these feelings exist, but how they are approached. Rather than treating jealousy as something to eliminate, many people in ENM learn to understand what it’s pointing to. It might be a need for reassurance, clarity, time, or emotional connection. The aim is not to suppress these feelings, but to respond to them with awareness.

If you’re curious about ENM… 

If ENM feels like something you want to explore, start with reflection. Ask yourself what draws you to this idea. Is it curiosity, a sense of restriction in monogamy, or a desire for different kinds of connection?

Honest Conversation

If you are in a relationship, honest conversation is essential. Not as a pitch or a negotiation tactic, but as sharing your thoughts and curiosities. It can help to focus on “this is what I notice in myself” rather than “this is what I want us to change immediately”.

Discomfort is likely to come up again and again, and that’s not always a bad thing. When it does come up, it can help to name it directly and clearly. For example, “I am noticing I need more reassurance around this.” There are lots of other tips for having more effective conversations here.

Boundaries

Boundaries are also key. In ENM relationships, they are not about control, but about clarity and supporting your relationships. Boundaries might include agreements around safer sex, time allocation, emotional transparency, or what information is shared between partners.

Go Slow

It can also be helpful to move at a slower pace than your curiosity suggests. New relationship energy (NRE) can be intense, and it’s easy to make decisions in that intensity that deserve a bit more time. Pausing, reflecting, and checking in with yourself regularly can make a big difference.

At its core, ENM is not about doing relationships “correctly”. It is about building relationship structures that actually fit the people involved, rather than forcing people to fit the structure.
