When does polyamory become a form of harm?

Emotional pressure, uneven desire, and Lindy West

Painting by Valeria Duca

Lindy West’s Adult Braces has become a small flashpoint in a much larger argument. By most accounts, West’s book is a memoir of a relationship that shifts from monogamy into nonmonogamy and eventually into a more stable triadic form. What unsettles readers isn’t the transition itself, but its texture. West didn’t initially desire nonmonogamy. She arrived there through resistance, distress, and a series of negotiations with herself about what it means to stay with someone who wants to pursue other romantic relationships. What gives the book its charge is that she stays long enough to narrate that adaptation as meaningful.

Some readers have taken this as a story about growth, the capacity to expand one’s understanding of love beyond possessiveness, to metabolize discomfort into a more capacious relational life. Others read the same material and see something closer to capitulation, a woman learning to narrate an unwanted condition as meaningful in order to endure it. (This is a generous way of putting it— some call it straight up emotional abuse).

Predictably, the disagreement has been framed as a referendum on polyamory itself. Is it liberatory or delusional? Ethical or self-serving? Realistic or corrosive? That framing is both too large and too blunt for what’s actually provoking such a sharp response.

The more precise question, the one the book seems to expose without resolving, is what do we do with situations in which two people share the same critique of monogamy, the same language of openness and autonomy, and yet find that their desires organize themselves in fundamentally different ways?

I know what this feels like: to stay long enough to see the difference between negotiation and endurance.

I was with my ex-husband for sixteen years. Toward the end of that marriage, we opened it. This decision emerged, as these things often do, from a deadened sexual dynamic and a shared intellectual framework: a sense that monogamy was historically contingent, that exclusivity placed too much pressure on a single relationship, that desire might not be built to sustain lifelong containment. We approached nonmonogamy in good faith, with care, with language, with a mutual desire to be honest about what we wanted.

What became clear, not immediately but very quickly in practice, was that the structure we thought we were agreeing to wasn’t actually shared. I no longer desired him, and I didn’t mind him sleeping with other people. He, meanwhile, still desired me, and found that he couldn’t tolerate the same freedom in the other direction. The arrangement was, in effect, asymmetrical from the start: permissive in theory, but only stable so long as it moved one way.

This is another version of the problem that often gets flattened in abstract discussions of nonmonogamy. It’s not something you agree to one time and settle; it’s an ongoing question of whether the conditions of that agreement are livable for both. In our case, the structure held only under a specific configuration of desire (mine absent, his intact) and collapsed as soon as that configuration shifted. What we had was a temporary alignment of tolerances.

This is the part that’s difficult to capture from the outside. There was no antagonist. No one was being manipulated or deceived. But the arrangement required something different from each of us. For me, it meant expansion. For him, it meant ongoing internal adjustment, an attempt to metabolize rejection that didn’t resolve with time.

That distinction only becomes visible over duration. You can agree to a structure. You can even believe in it. But living inside it, repeatedly, with stakes, reveals something else: whether the cost of that agreement distributes evenly, or whether it settles, persistently, in one person’s body.

We eventually separated. In our case, nonmonogamy exposed a mismatch that could only be sustained if one of us adapted more than the other.

I encountered a quieter version of that same structure later, in a much shorter relationship. Here, nonmonogamy was never fully enacted. What existed instead was its possibility: a standing preference on his part for openness, and a provisional agreement on mine to monogamy with an asterisk. The structure was latent rather than lived, but it wasn’t neutral.

I found myself responding not to what was happening, but to what could happen. My attention reorganized around a condition that hadn’t yet materialized. I looked for his messages. I replayed conversations. My desire, which I had long understood as diffuse and novelty-seeking, did something profoundly uninteresting: it settled. I wasn’t scanning rooms or refreshing apps or wondering what else might be available. I wanted him, specifically, with a kind of quiet insistence that felt less like a decision than a fact.

He was kind and honest, neither evasive nor withholding. He believed nonmonogamy was more ethical, more realistic, more aligned with how desire actually works. I believed most of these things too, at least cognitively. I could make that case fluently. What I couldn’t do was make my nervous system agree.

At one point I tried to correct for this by going on a date with someone else. He was attractive and attentive. Instead of wanting him, I found myself thinking, with some irritation, that I would rather be talking to the person I was already invested in. It felt narrow, almost stubborn, as though my desire had decided, without consulting my politics, that it had found enough.

One of the quieter cruelties of my internal discourse was my habit of treating discomfort as evidence of insufficient analysis. Feeling destabilized became proof that I hadn’t fully interrogated my attachment patterns, my residual investments in exclusivity. The implication was that a well-adjusted person wouldn’t feel this way, or would feel it briefly and then convert it into flexibility. Distress became a sign of lagging development.

But what if that story is wrong? What if some forms of desire consolidate with care? What if attention narrows not because we are regressive or afraid, but because we are responsive? What if convergence is a form of attunement?

This is the part of the conversation that tends to disappear in the current discourse. We’re relatively comfortable debating whether polyamory is valid in the abstract. We are less equipped to talk about what happens when two people endorse the same critique but inhabit different affective architectures. These positions aren’t fixed—I’ve occupied both—but when they don’t align within the same relationship, the result isn’t automatically more honesty or more freedom. It’s uneven. And that unevenness has to be carried somewhere.

In practice, nonmonogamy often relocates that burden onto the individual nervous system. It privileges adaptability, resilience, and self-management: the ability to metabolize instability internally rather than negotiate it structurally. Discomfort becomes something to process, to work through, to outgrow. The structure remains intact; the subject adjusts. This isn’t unique to nonmonogamy, but it’s often intensified within it, especially in spaces where openness functions less as one option among others and more as an ethical standard.

That dynamic had its own texture in the much shorter relationship, where the threat was latent rather than enacted, but my nervous system didn’t register that distinction. I wasn’t responding to what he was doing. I was responding to what the structure permitted, what remained available to him by preference, even when not exercised. The anxiety was about contingency. The monogamy we eventually agreed to felt less like a shared condition than like a favor that could, at any point, be reconsidered.

No one was exploiting me. But there was a form of pressure that’s easy to miss because it doesn’t look like force. It looks like an asymmetry of stakes. If I refused the arrangement, I risked losing the relationship. If I agreed, I absorbed a form of ongoing internal strain. Emotional pressure, in this sense, doesn’t require anyone to do anything wrong. It emerges when the cost of refusal is relational loss and the cost of agreement is a sustained misalignment with one’s own responses.

Wanting singularly may be a pattern that carries its own legitimacy, even when it complicates our preferred theories of how love should work. What Adult Braces surfaces, and what the discourse around it keeps skirting, is something simpler and harder: agreement isn’t the end of the question. It’s the beginning of a longer one about what that yes requires, and who is asked to keep paying for it.
