Is He Having an Affair or Just Avoidant? What I Overheard in a Coffee Shop

by Helena Marston  - March 17, 2026

Is your husband or wife cheating, or just avoidant under stress? Learn the difference between affair signs and avoidant attachment—and how to stop the anxious-avoidant cycle before it destroys your marriage.

I couldn't help but wonder: Why do we ask friends to diagnose our relationships when they're no more trained than we are—and twice as likely to catastrophize?


I was in a London coffee shop recently, wedged between client sessions, when I overheard a conversation that made me want to lean over and say: 'Stop. You're both wrong.’

If you've ever Googled "is my husband cheating" because he's gone cold, you need to read this.

A woman—let's call her Latte—was telling her friend Chino that she thought her husband Mark was having an affair.

The evidence? He'd become distant. Defensive. Working longer hours. Protective of his phone. Their sex life had gone from connected to mechanical. He was lighter when they were out socially, flat the moment they got home. All classic signs of an emotionally distant husband—but they're also classic signs of avoidant attachment under stress.

Chino's response? Immediate validation of every fear.

"That's not normal newlywed behavior. Men don't withdraw like that unless they've mentally checked out. The defensiveness about his phone? Classic. If he wasn't hiding something, he wouldn't react like you're interrogating him."

I wanted to reach over and muzzle her.

 Not because she was being a bad friend—but because she was being a terrible diagnostician.

The "Evidence" That Screams Affair (But Isn't)

Here's what Latte told Chino—and here's what I heard while trying not to roll my eyes:

Mark had become emotionally withdrawn. They used to cook dinner together and talk about their days. Now when she asked how work was? "Fine." Subject change.

He was defensive about his phone. Turned it face down. Took calls in another room. Got irritated when she asked who he was texting. (Classic affair behavior, right? That's what Chino thought.)

He'd stopped arguing. Previously, if she didn't want to see his mother, he'd lovingly convince her. Now? "Okay." Done. (Chino's interpretation: He doesn't care anymore.)

He was lighter when they were out socially. At dinner with neighbors, he was his usual charming self. The moment they walked through their front door? Flat. (To Latte: He's happier away from me.)

Their sex life had become strange. Either he was "too tired" or it felt oddly disconnected—efficient but not intimate. (Chino's verdict: He's getting it elsewhere.)

The work stress excuse had lasted six months. He kept saying he was buried with a big project. But six months? Come on. (Convenient, right?)

To Latte—and to Chino—this looked like a textbook case of a man who was either done with his marriage or had someone else.

They were building an airtight case.

And they were completely wrong.

Here’s what they both missed.

4 Breadcrumbs I Heard Over My Espresso (That Chino Completely Missed)

While Latte was building her affair case, she kept casually dropping breadcrumbs that told a completely different story.

And I was collecting every single one.

Breadcrumb #1: When they were dating, Mark always disappeared into work when he was stressed. Not her—she sought comfort in him. But Mark? He went quiet and handled things alone. He's always been like this.

Breadcrumb #2: He'd always taken ages to text back. He'd never been into talking about his feelings. She'd always had to draw things out of him. This isn't new behavior.

Breadcrumb #3: He was starting to act like his parents—cold, detached people who'd sent him to boarding school at age 10. This is learned behavior, not betrayal.

Breadcrumb #4: While he'd always said he wanted kids, he got weird whenever she tried to talk about actually starting a family. He avoids vulnerability. Always has.

By the time Latte finished her second coffee, the pattern was crystal clear to me:

Latte had married Mark hoping he'd change. Hoping marriage would make him more affectionate, more emotionally available, more willing to talk about feelings.

But Mark hadn't changed.

Mark was being Mark.

The same man he'd always been—just under more pressure than usual.

What's Actually Happening: Avoidant Attachment Under Stress

Mark isn't having an affair.

Mark is avoidantly attached. And he's stressed as hell.

Here's what that means:

When avoidant people get overwhelmed, they don't reach for connection. They shut it down.

Why? Because somewhere back in childhood, they learned: "I have to handle things on my own. Needing people is risky. Self-reliance is safer."

So when work stress hits, Mark's nervous system doesn't think: "Talk to Latte. She'll help."

It thinks: "Reduce emotional exposure. Stay in control. Handle this alone."

That's why he:

  • Stops talking about his day (withdrawal)
  • Gets irritable at questions (feels like surveillance, not care)
  • Guards his phone obsessively (needs autonomy)
  • Buries himself in work (safe—no emotional intimacy required)
  • Goes mechanical in bed (sex = vulnerability = too much)

To Mark, the marriage isn't a safe harbor right now.

It's the place that requires the most vulnerability—when he's already maxed out.

So he pulls back.

Not because he doesn't love Latte.

Because closeness feels destabilizing when you're barely holding it together.

Why Anxious Attachment Reads Distance as Danger

Now add Latte's side of the equation.

She's anxiously attached. Which means her nervous system is constantly scanning for threats to connection.

Childhood taught her: "Stay alert. If you're not paying attention, you might lose them."

So when Mark becomes quieter, flatter, more defensive, more withdrawn—Latte's brain doesn't think: "He's stressed."

It thinks: "He's leaving."

Every small shift in his behaviour feels catastrophic:

  • He's pulling away → "I've done something wrong"
  • He's lighter when we're out → "He's happier away from me"
  • He won't talk → "He doesn't want me anymore"
  • He's protective of his phone → "There must be someone else"

And here's the thing: "affair" is psychologically cleaner than "our attachment styles are colliding."

It gives her something concrete. Something that makes sense of the pain.

So her interpretation isn't irrational.

It's protective.

She's not crazy. She's dysregulated.

And the more she reaches for reassurance, the more Mark pulls back.

The more he pulls back, the more she panics.

That's the cycle. And it escalates fast.

3 Behaviors Decoded: Affair or Avoidant?

Let me show you what Latte’s “evidence” actually mean and how to decode avoidant partner behavior when you're spiraling.


1. He's Lighter When He's Out Socially

What Latte thought: "He's happier away from me."

What's actually happening: Social situations have zero attachment pressure. He can perform—be charming, be "on"—without anyone expecting him to be vulnerable.

At home? Latte wants connection. She wants him to open up. And when he's already maxed out, that feels like more demand.

2. He Stopped Arguing and Just Says "Whatever You Think"

What Latte thought: "He doesn't care anymore."

What's actually happening: Conflict feels engulfing when you're avoidant and stressed. Arguing requires emotional energy he doesn't have.

So he disengages.

It's not apathy. It's survival.

3. Sex Is Either Mechanical or Guilt-Driven

What Latte thought: "He's getting it elsewhere."

What's actually happening: Sex activates vulnerability. When Mark's stressed, sex feels like another performance he might fail at.

So it becomes either:

  • Mechanical (efficient, low-risk, contained)
  • Guilt-driven (overcompensating to avoid conflict)

Neither feels connected. Because connection requires emotional availability he doesn't have right now.

What I'd Tell Latte (If She'd Asked Espresso Instead of Chino)

If Latte had turned to me instead of Chino, here's what I would have said:

"Mark's probably not cheating. But this IS a problem."

What's happening isn't betrayal.

It's two nervous systems colliding under pressure.

Mark's avoidant system: "Shut down. Handle it alone."

Latte's anxious system: "Monitor closely. Something's wrong."

The more she reaches, the more he retreats. The more he retreats, the more she panics.

That's the cycle. And it won't fix itself.

So what would I tell her to do?

What to Do When He Withdraws (And What Never To Do)

Here's what I'd tell her to try:

Stop chasing him when he withdraws.

I know that feels impossible. Every instinct screams: "Get closer. Fix this. Make him talk."

But chasing an avoidant person when they're stressed makes them retreat harder. It's like trying to catch a cat by running at it—counterproductive and exhausting.

Instead, try this:

"I've noticed you've been quieter lately. I'm guessing work is brutal right now. I'm here if you want to talk—but I also get it if you need space."

This names what's happening without accusation, and gives him the autonomy his nervous system desperately needs.

Ask what he needs instead of assuming.

"Do you need space, or would it help to talk?"

Then actually listen to the answer. Don't interpret silence as rejection. Sometimes silence is just silence.

Stop trying to force the conversation.

You cannot talk someone into being emotionally available. The harder you push, the further they retreat.

When you feel the urge to demand a conversation, try this instead:

"I can see you're not ready to talk. I'm going to stop asking for now, but I'm still here when you are. In the meantime, I need to focus on not spiraling."

Then actually do it. Go for a walk. Call a regulated friend (not Chino). Tend to your own nervous system.

What you're doing is breaking the pursue-withdraw cycle. When you stop chasing:

He stops feeling hunted, which lowers his defensiveness

You stop dysregulating yourself, which gives you clarity

He may still not talk immediately. But you'll be calmer. And calm people make better decisions than anxious ones.

How to tell if he's "needing space" or "shutting you out permanently"

Ask yourself: does he eventually return?

Needing space: He withdraws for an evening, a few days, maybe a week—then gradually re-engages. He might not explain the withdrawal, but he comes back to warmth and connection.

Shutting you out: The withdrawal keeps extending. No re-engagement. No warmth. You're always the one initiating. The distance feels permanent, not temporary.

The difference is motion. Temporary space has a rhythm. Permanent shutdown has stillness.

If you're unsure, test it gently after giving him space: "Fancy a walk later? No pressure if you're still in work mode."

If he declines but offers an alternative: he's returning

If he declines repeatedly with no alternative for weeks: he's not coming back on his own

When to get professional help

If you're wondering "is my marriage over" because he's been gone this long, don't guess—get support.

Six to eight weeks of active withdrawal.

By "active withdrawal" I mean:

Emotionally flat or absent most of the time

Not initiating any connection

Deflecting or shutting down when you raise concerns

You've stopped chasing, but he hasn't retured

If that's been your pattern for two months, you need backup. Not because your marriage is doomed—but because the DIY approach isn't working.

Avoidant partners often can't articulate what they need even to themselves. A skilled therapist creates a container where he can feel safe enough to speak, and you can feel safe enough to hear it without your anxiety hijacking the conversation.

Regulate your own nervous system before you try to fix his.

Your anxiety is valid. But if you're operating from panic, every conversation becomes an interrogation.

Before you say anything, ask yourself: "Am I calm enough to have this conversation—or am I just trying to stop my own anxiety?"

Get support outside the relationship.

Not from Chino.

From someone who can help you see the pattern instead of validating every fear.

Because here's the brutal truth: friends like Chino mean well, but they're not trained to diagnose.

They're trained to care. And sometimes caring looks like validation—even when validation is the last thing you need.

See your own patterns.

If you're anxiously attached, you're going to read distance as abandonment. Every single time.

That's not weakness. That's wiring.

But if you can see it clearly, you can start to interrupt the cycle instead of feeding it.

Why Friends Make Terrible Relationship Diagnosticians

Here's what this coffee shop conversation reminded me:

Most people are diagnosing their relationships based on fear, not data.

Latte wasn't wrong to notice Mark's withdrawal. She wasn't wrong to feel concerned.

But without a framework to understand what was actually happening, her mind filled in the gaps with the worst-case scenario.

And Chino—well-meaning as she was—confirmed every fear instead of helping Latte see the pattern.

That's the problem with asking friends for relationship advice.

Real relationship advice for anxious attachment isn't validation—it's clarity. Friends validate. They empathize. They tell you what you want to hear.

But they don't see:

  • Attachment dynamics
  • Nervous system responses
  • The gap between what's happening and what it looks like

Relationships don't survive on love and good intentions alone.

They survive on clarity.

Clarity about what's actually broken. Clarity about your patterns. Clarity about what needs to change.

Get Clarity: See What You Can't See

If Latte's story sounds familiar—if you've ever wondered whether your partner is pulling away, checked out, or hiding something—you're not alone.

And you're not crazy.

But you might be diagnosing a problem you can't see clearly.

That's what the Relational Intelligence Assessment does.

It shows you:

  • Your attachment patterns (and your partner's)
  • The exact dynamics keeping you stuck
  • What's actually driving the conflict—not just what it looks like

Not guessing. Not catastrophizing. Not asking Chino.

Just clarity.

Because you can't fix what you can't see.

Stop wondering "is he avoidant or just not that into me." Get data.
