Can You Go the Distance? – The 100-Mile Rule in Polyamory

Polyamory invites us to rethink what commitment, connection, and boundaries can look like outside of traditional relationship structures. With that freedom, however, comes the need for clear communication and intentional agreements. One concept that often sparks curiosity—and sometimes controversy—is the “100-mile rule.”

So, what is it? And more importantly, can it be practiced ethically?

What Is the 100-Mile Rule?

The “100-mile rule” is an agreement some people in polyamorous or ethically non-monogamous (ENM) relationships use to define where additional partners can be located. In its simplest form, it means that partners agree not to pursue romantic or sexual connections within a 100-mile radius of their shared home or primary relationship.

The reasoning behind this rule often includes:

• Reducing overlap in social circles

• Avoiding awkward or emotionally complex encounters

• Maintaining a sense of separation between different relationships

• Creating a feeling of safety or containment for a primary partnership

For some, distance can feel like a buffer that makes navigating multiple relationships less overwhelming.

Why Do People Consider It?

At its core, the 100-mile rule is often about managing discomfort and uncertainty. Polyamory can bring up fears around comparison, visibility, and emotional security. A distance-based agreement can feel like a way to:

• Protect shared spaces (friend groups, workplaces, neighborhoods)

• Reduce the likelihood of running into a partner’s other partner unexpectedly

• Maintain a sense of privacy

It can also be appealing for people newer to polyamory who are still building trust and emotional regulation skills.

How to Ethically Implement the 100-Mile Rule

Like any relationship agreement, the ethicality of the 100-mile rule doesn’t come from the rule itself; it comes from how it’s created, discussed, and upheld.

Here are some key considerations:

1. Mutual Consent, Not Coercion

Both (or all) partners should freely agree to the rule. If one person feels pressured, resentful, or restricted, that’s a sign the agreement may not be truly consensual.

2. Clarity and Specificity

What counts as “within 100 miles”? Is it based on home address, city limits, or travel time? What happens if someone moves? Clear definitions prevent misunderstandings.

3. Flexibility and Reassessment

People, relationships, and comfort levels evolve. Build in regular check-ins to revisit whether the rule is still serving everyone involved.

4. Avoiding Control Disguised as Boundaries

A boundary is something you set for yourself; a rule is something placed on others. Ethical implementation means examining whether this agreement is about personal needs or about controlling a partner’s behavior.

5. Transparency With Other Partners

If you’re dating others, they deserve to know about any limitations that might affect the relationship. Hidden rules can create confusion or feelings of being devalued.

Is the 100-Mile Rule Ethical?

The short answer: it depends.

The longer answer: The ethics of the 100-mile rule aren’t inherent; they’re contextual.

On one hand, it can be a mutually agreed-upon structure that helps partners feel secure, especially in the early stages of exploring polyamory. When approached collaboratively and revisited regularly, it can function as a temporary support rather than a rigid restriction.

On the other hand, it can become problematic if:

• It limits autonomy in a way that feels unfair or one-sided

• It’s used to avoid doing deeper emotional work (e.g., jealousy, insecurity)

• It creates a hierarchy that devalues other partners

• It restricts meaningful connections based solely on geography rather than compatibility

In some cases, the rule may unintentionally send the message: “Other relationships are only acceptable if they don’t feel too real or too close.” That can be hurtful, not only to additional partners but also to the integrity of the relationship structure itself.

Centering Personal Choice

At the heart of ethical non-monogamy is informed, enthusiastic consent and personal agency.

No single rule works for everyone. Some people thrive with structure; others feel constrained by it. The key questions to ask are:

• Does this agreement align with my values?

• Am I choosing this freely, or agreeing out of fear?

• Does this support growth, or avoid discomfort?

• How does this impact everyone involved—not just the primary partnership?

Choosing whether or not to implement something like the 100-mile rule should come from a place of self-awareness, communication, and respect for all partners’ autonomy.

Final Thoughts

The 100-mile rule isn’t inherently good or bad. It’s simply a tool. Like any tool, its impact depends on how it’s used.

If it helps create safety while you build trust, it may have a place in your relationship. But if it limits connection, reinforces insecurity, or feels controlling, it might be worth exploring what’s underneath that need.

Polyamory isn’t about avoiding discomfort altogether; it’s about learning how to navigate it with honesty, care, and intention.

Because ultimately, the question isn’t just “Can you go the distance?”

It’s “Can you stay connected—ethically and authentically—no matter the distance?”
