Polyamory is becoming more popular. Is an open marriage for me?

Editor’s note, June 14, 8 am ET: We’re bringing you some of our best-loved Your Mileage May Vary columns while Sigal Samuel is on parental leave. The one below originally published on June 8, 2025.

This unconventional advice column offers you a unique framework for thinking through moral dilemmas. It’s based on value pluralism: the idea that each of us has multiple values that are equally valid but that often conflict with each other. Stay tuned for more original Your Mileage May Vary columns coming in June. In the meantime, submit your own question here.

My husband and I have a good relationship. We’re both committed to personal growth and continual learning and have developed very strong communication skills. A couple of years ago we were exposed to some friends with an open marriage and had our own conversations about ethical non-monogamy. At first, neither of us were interested.

Now, my husband is interested and currently is attracted to a colleague who is also into him. She’s married and has no idea that he and I talk about all of their interactions. He doesn’t know what her relationship agreements are with her husband.

I’m not currently interested in ethical non-monogamy. I see things in our relationship that I’d like to work on together with my husband. I want more of his attention and energy, to be frank. I don’t want his attention and energy being funneled into another relationship. I don’t have moral issues with ethical non-monogamy, I just don’t actually see any value-add for me right now. The cost-benefit analysis leaves me saying “not now.”

My husband admitted that he’s hoping I will have a change of mind. I don’t want to force his hand, although I am continuing to say very clearly what I want in my relationship. How do we reach a compromise? If he cuts ties with this woman, he has resentment towards me. If he continues to pursue something with her, I feel disrespected, and while I don’t want to leave him I would feel the need to do something.

Dear Monogamously Married,

I want to start by commending you for two things. First, for your openness to discussing and exploring all this with your husband. Second, for your insistence on clearly stating what you actually want — and don’t want.

I think Erich Fromm, the 20th-century German philosopher and psychologist, would back me up in saying that you’d do well to hold tight to both those qualities. For starters, radical openness is important because, according to Fromm, the basic premise of love is freedom. He writes:

Love is a passionate affirmation of its “object.” That means that love is not an “affect” but an active striving, the aim of which is the happiness, development, and freedom of its “object.”

In other words, love is not a feeling. It’s work, and the work of love is to fully support the flourishing of the person you love. That can be scary — what if the person discovers that they’re actually happier with somebody else? — which is why Fromm specifies that only someone with a strong self “which can stand alone and bear solitude” will be up for the job. He continues:

This passionate affirmation is not possible if one’s own self is crippled, since genuine affirmation is always rooted in strength. The person whose self is thwarted can only love in an ambivalent way; that is, with the strong part of his self he can love, with the crippled part he must hate.

So far, it might sound like Fromm is saying that to be a good lover is to be a doormat: You just have to do whatever’s best for the other person, even if it screws you over. But his view is very much the opposite.

In fact, Fromm cautions us against both “masochistic love” and “sadistic love.” In the first, you give up your self and sacrifice your needs in order to become submerged in another person. In the second, you try to exert power over the other person. Both of these are rooted in “a deep anxiety and an inability to stand alone,” writes Fromm; whether by dissolving yourself into them or by controlling them, you’re trying to make it impossible for the other person to abandon you. Both approaches are “pseudo-love.”

So although Fromm doesn’t want you to try to control your partner, and although he suggests that the philosophical ideal is for you to passionately affirm your partner’s freedom, he’s not advising you to do that if, for you, that will mean masochism.

If you’re not up for ethical non-monogamy — if you feel, like many people, that the idea of giving your partner free rein is too big a threat to your relationship or your own well-being — then pretending otherwise is not real love. It’s just masochistic self-annihilation.

I’m personally partial to Fromm’s non-possessive approach to love. But I equally appreciate his point that the philosophical ideal could become a practical bloodbath if it doesn’t work for the actual humans involved. I think the question, then, is this: Do you think it’s possible for you to get to a place where you genuinely feel ready for and interested in ethical non-monogamy?

It sounds like you’re intellectually open to the idea, and given that you said you’re committed to personal growth and continual learning, non-monogamy could offer you some benefits; lots of people who practice it say that part of its appeal lies in the growth it catalyzes. And if practicing non-monogamy makes you and/or your husband more fulfilled, it could enrich your relationship and deepen your appreciation for each other.

But right now, you’ve got a problem: Your husband is pushing on your boundaries by flirting with a woman even after you’ve expressed that you don’t want him pursuing something with her. And you already feel like he isn’t giving you enough attention and energy, so the prospect of having to divvy up those resources with another woman feels threatening. Fair!

Notice, though, that that isn’t a worry about non-monogamy per se — it’s a worry about the state of your current monogamous relationship.

In a marriage, what partners typically want is to feel emotionally secure. But that comes from how consistently and lovingly we show up for and attune to one another, not from the relationship structure. A monogamous marriage may give us some feeling of security, but it’s obviously no guarantee; some people cheat, some get divorced, and some stay loyally married while neglecting their partner emotionally.

“Monogamy can serve as a stand-in for actual secure attachment,” writes therapist Jessica Fern in Polysecure, a book on how to build healthy non-monogamous relationships. She urges readers to take an honest look at any relationship insecurities or dissatisfactions that are being disguised by monogamy, and work with partners to strengthen the emotional experience of the relationship.

Since you feel that your husband isn’t giving you enough attention and energy, be sure to talk to him about it. Explain that it doesn’t feel safe for you to open up the relationship without him doing more to be fully present with you and to make you feel understood and precious. See if he starts implementing these skills more reliably.

In the meantime, while you two are trying to reset your relationship, it’s absolutely reasonable to ask him to cool it with the colleague he’s attracted to; he doesn’t have to cut ties with her entirely (and may not be able to if they work together), but he can certainly avoid feeding the flames with flirtation. Right now, the fantasy of her is a distraction from the work he needs to be doing to improve the reality of your marriage. He should understand why a healthy practice of ethical non-monogamy can’t emerge from a situation where he’s pushing things too far with someone else before you’ve agreed to change the terms of your relationship (and if he doesn’t, have him read Polysecure!).

It’s probably a good idea for you to each do your own inner work, too. Fern, like Fromm, insists that if we want to be capable of a secure attachment with someone else, we need to cultivate that within ourselves. That means being aware of our feelings, desires, and needs, and knowing how to tend to them. Understanding your attachment style can help with this; for example, if you’re anxiously attached and you very often reach out to your partner for reassurance, you can practice spending time alone.

After taking some time to work on these interpersonal and intrapersonal skills, come back together to discuss how you’re feeling. Do you feel more receptive to opening up the relationship? Do you think it would add more than it would subtract?

If the answer is “yes” or “maybe,” you can create a temporary relationship structure — or “vessel,” as Fern calls it — to help you ease into non-monogamy. One option is to adopt a staggered approach to dating, where one partner (typically the more hesitant one) starts dating new people first, and the other partner starts after a predetermined amount of time. Another option is to try a months-long experiment where both partners initially engage in certain romantic or sexual experiences that are less triggering to each other, then assess what worked and what didn’t, and go from there.

If the answer is “no” — if you’re not receptive to opening up your relationship — then by all means say that! Given you’ll have sincerely done the work to explore whether non-monogamy works for you, your husband doesn’t get to resent you. He can be sad, he can be disappointed, and he can choose to leave if the outcome is intolerable to him. But he’ll have to respect you, and what’s more important, you’ll have to respect yourself.
