Should Married Couples Be Concerned About Opposite-Sex Friendships?
Are you comfortable with your spouse having a “best friend” of the opposite sex?
This was the question of the night during a holiday meet-and-greet hosted by one of my favorite local boutiques (shoutout to Boutique Outlet in Winter Haven, Florida, and its fabulous owner, Ms. Que!). The event brought together local vendors for a fun, festive evening, and naturally, some juicy conversations unfolded.
For a little research (and a lot of curiosity), I posed this question to the ladies in the room:
“Would you be comfortable with your husband having a single woman as a best friend?”
Whew! Let me tell you, the responses came in hot! Emotions ran high, and opinions were flying. About 80% of the women stated they would NOT be comfortable. Their reasons? It depended on factors like:
- Is she friends with the wife, too?
- Did the friendship start before the marriage?
- Is she attractive? (Because, let’s be honest, that does cross some minds!)
- Were they ever a couple or intimate in the past?
- Is there a current attraction or secret crush happening?
The remaining 20% had mixed emotions about it.
Marriage and Friendship with the Opposite-Sex
One young lady shared that she was actually in this situation. She had an unmarried, attractive male friend she regularly went out with for drinks, dancing, etc., Her perspective? If her husband had an issue, that was his problem. As the ladies probed a little further, she confessed that her ‘bestie’ has had a crush on her for years now.
My husband jokingly calls these types of attachments the “break glass in case of emergency” relationships—and it’s a fitting analogy. Here’s the breakdown: this is the kind of opposite-sex friendship where the guy sticks around in the background, seemingly harmless, but he’s low-key positioning himself as the backup plan.
In these situations, he plays the role of the supportive bestie, the one she turns to when things aren’t going smoothly in her relationship. He’ll be her listening ear, her comfort, and her shoulder to lean on. On the surface, their relationship stays within appropriate boundaries—no flirting, no crossing the line—but the dynamic can get tricky when emotional dependence grows.
And here’s where the “breaking the glass” comes in: if she suddenly needs more from him—whether it’s emotional intimacy, validation, or even physical comfort—he’s ready to step in. The friendship that seemed so innocent can quickly become something more, especially during vulnerable moments when judgment is clouded.
It’s not about saying all opposite-sex friendships have this hidden agenda, but let’s be real—some do. The key is awareness and boundaries. Is the friendship balanced and respectful of the marriage, or is one person quietly waiting for an opportunity?
This is why communication and trust in marriage are so important. If a friendship starts to feel like a safety net instead of a simple connection, it’s worth addressing. Because no one wants to feel like their spouse has someone “waiting in the wings.” Would you agree?
Marriage Boundaries
Let’s talk about boundaries. Every marriage needs them, and opposite-sex friendships are no exception. Make sure you and your spouse are on the same page about what feels comfortable. For example, is texting late at night okay? Are solo outings off-limits? When going out, is dancing with another man acceptable?
Setting clear boundaries upfront helps protect the trust you’ve built.
Think of boundaries as the invisible lines that protect your relationship from outside influences while also ensuring you both feel valued. They define what’s okay and what’s not—whether it’s about friendships, family dynamics, finances, or intimacy.
Without boundaries, resentment and misunderstandings can creep in. For example, if one spouse has an opposite-sex friend and the other feels excluded or uncomfortable, that can create tension. Boundaries help set expectations and avoid unnecessary conflict.
How to Set Boundaries
- Start with a conversation. Share your needs and listen to your partner’s.
- Be specific. Instead of vague statements like, “Don’t cross the line,” define what the line is.
- Stay consistent. Boundaries only work if you both honor them.
- Be flexible. Life changes, and sometimes boundaries need adjusting.
Boundaries aren’t about saying “no” to love—they’re about saying “yes” to a stronger, healthier connection.
Navigating Trust: Married Life and Unmarried Opposite-Sex Friends
Is it about a lack of trust in your marriage? Opposite-sex friendships in marriage can be tricky to navigate. Whether it’s your spouse’s bestie or your own, these relationships often stir up questions about boundaries, trust, and respect. So, how do we handle them without unnecessary drama?
First, it’s all about open communication. If your spouse has an unmarried friend of the opposite sex, ask yourself: Are there clear boundaries in place? Do I feel included or shut out? Relationships thrive on honesty, so make space to talk about any discomfort you might feel without jumping to conclusions.
Next, consider the history of the friendship. Did it exist before your marriage? Has this friend been respectful of your relationship? If they’ve always been a supportive, platonic presence, there may not be much to worry about. But if there’s been past intimacy or questionable behavior, it’s worth having a deeper discussion. If your spouse’s friend is respectful of your marriage, they should have no problem including you in their friendship. Mutual respect fosters trust, and no one should feel like they’re on the outside looking in.
Finally, let’s not forget the role of self-confidence. Trust starts within. If you’re feeling insecure, take a moment to reflect on why. Are these fears grounded in reality, or are they tied to past experiences?
Marriage is built on trust, respect, and communication. As long as those pillars stay strong, navigating opposite-sex friendships doesn’t have to be a dealbreaker.
Conclusion
While at the boutique, one woman shared a powerful example from her own life. She explained how she had to step back from a previous opposite-sex best friend—not because her husband asked her to, but because she realized it wasn’t the best idea. Over time, she noticed the friendship might be crossing emotional boundaries that could unintentionally impact her marriage. Out of respect for her relationship and her own intuition, she made the choice to distance herself, recognizing that some connections, no matter how innocent, can blur the lines when you’re committed to building a strong partnership.
By the end of the night, the room came to an important conclusion: every relationship is unique. What works for one couple might not work for another, and that’s okay. For some marriages, opposite-sex friendships can be healthy and manageable with clear boundaries and open communication. For others, they may introduce unnecessary complications or insecurities.
The key takeaway? It’s about understanding what feels right for your marriage. Each couple has to decide together what’s acceptable and comfortable based on their own values, trust, and dynamics. There’s no one-size-fits-all rulebook when it comes to balancing friendships and protecting your relationship.
What works in your marriage may not work in someone else’s—and that’s perfectly okay.
