What Openness Requires
Most people don't choose their relationship structure. They inherit it.
Monogamy is the assumed architecture of romantic partnership in most of the cultural contexts I work in — the default, the expectation that doesn't require negotiation because it’s simply what relationships are. Couples slide into it not through an explicit decision, but because it’s the form that was modeled, available and morally sanctioned.
Monogamy is a perfectly fine relationship structure, but monogamists could learn a lot from consensual non-monogamy. It requires a high degree of intentionality, from the very beginning. You cannot practice it by default. You have to choose it, name it, negotiate it, and keep renegotiating it as the relationship evolves.
This tends to make it uniquely clarifying. And uniquely demanding.
Consensual non-monogamy is an umbrella term, and it covers a range of relationship structures that differ meaningfully from each other.
Open relationships, in which partners may have sexual relationships with others.
Polyamory, in which partners may form romantic and emotional connections — not just sexual ones — with multiple people.
Relationship anarchy, which rejects hierarchies among relationships altogether.
These aren’t interchangeable, and someone navigating polyamory and someone in an open relationship may be experiencing very different terrain.
What they share is this: some form of explicit agreement between the people involved, some degree of transparency about outside connections, and — crucially — the consent of everyone participating to the structure they're in. The "consensual" in consensual non-monogamy is doing real work. It’s what distinguishes this from infidelity, which is also non-monogamy, but without the knowledge or agreement of everyone involved.
The couples and individuals who come to therapy around CNM tend to arrive from a few different places.
Some are in monogamous relationships and one partner has raised the possibility of opening things up. The other may be uncertain, reluctant, or quietly frightened — not necessarily because they object philosophically, but because the idea surfaces fears they don't quite have language for yet. What does this mean about what we are? What does it mean about me? These conversations require honesty, careful pacing, and a real willingness to hear each other, and are often where therapy is most useful.
Some couples have already opened their relationship and are discovering that openness is more complicated in practice than in theory. Jealousy threatens to wreak havoc. Someone has developed feelings that weren't part of the original agreement. The logistics, which seemed manageable in the abstract, have become a source of conflict. Partners use therapy to support navigating something that is working in some ways and straining in others.
And some have opened the relationship in an attempt to repair it. Perhaps it was meant to bring in some new energy, to address a desire discrepancy, to keep a struggling partnership intact. This almost never works. Opening a relationship from a place of scarcity — when what's underneath is disconnection, resentment, or a desire to avoid a harder conversation — tends to amplify the underlying problems rather than resolve them.
CNM can be a generous and intentional way to structure a relationship. It is not, in my experience, an effective way to rescue one.
There’s a misconception I encounter fairly often: that open relationships require less of their participants than monogamous ones. In practice, the opposite tends to be true.
CNM doesn't eliminate the hard parts of partnership. It multiplies them — across more people, more feelings, more logistics, more potential for jealousy and misunderstanding and hurt. What it requires, more than perhaps any other relationship structure, is the ability to communicate with real honesty about what you’re feeling, what you want, what you can offer, and what you cannot. Not the careful, managed version of communication that many couples default to — the kind that prioritizes harmony over truth — but the more demanding kind that requires naming something uncomfortable before it becomes a crisis.
It also requires the ability to hold jealousy as information rather than catastrophe. Jealousy in a CNM relationship is not a sign that the structure has failed. It’s a signal about attachment needs, about something that may need attention in the primary relationship, about a fear that hasn't yet been spoken. Partners who learn to approach jealousy with curiosity rather than alarm tend to navigate this territory significantly better than those who expect it to simply go away.
Many people navigating consensual non-monogamy are intensely private about their relationships out of fear.
They may have encountered loved ones or even a therapist whose only framework was monogamy, who pathologized their structure, or who communicated — subtly or not — that their relationship was a problem to be solved rather than a context requiring care. That experience of not being seen is its own injury, and it keeps people from getting support they genuinely need.
CNM relationships deserve the same thoughtful, non-judgmental support as any other. The questions they bring — how to communicate when things are hard, how to navigate jealousy, how to keep a relationship strong while other connections develop, how to repair when something goes wrong — are recognizable relationship questions. They just occur in a context that many haven’t encountered or taken the time to understand.
The degree of intention that CNM requires is honorable.
To decide, explicitly and together, what kind of relationship you want to be in is a demanding undertaking. It requires honesty, self-knowledge, courage, and a commitment to personal growth. Those are good qualities to bring to any relationship, whatever shape that relationship takes. §
