In the fifth year of our marriage, I found a strand of hair in Brad Fox's car that wasn't mine.

Chestnut. Slightly wavy. Carrying the faintest trace of gardenia.

My hair is black and straight, and I use jasmine shampoo.

This strand was wound around the seatbelt buckle on the passenger side, wound tight.

As though someone had sat there countless times, leaving a little trace with each one, until it built up into this.

I didn't confront him on the spot.

Not because I'm generous. Because I knew the thing Brad hated most was a scene over nothing.

He'd frown and say, "Isn't it perfectly normal for someone to have ridden in the car? A coworker catches a ride, and you're going to make an issue of it?"

Then he'd look at me with that "how can you be so unreasonable" expression, until I'd feel like I really was blowing things out of proportion.

……

That's how it had always been. Every time, he'd shut me down, and I'd start doubting myself, wondering if I was just too sensitive, too petty, too quick to crowd him.

But this time, I didn't doubt myself.

I put that strand of hair into a sealed bag and tucked it into a drawer.

Then I started paying attention.

Over the past six months, Brad had changed a great deal.

He used to walk straight into his study when he got home. Now he'd sit in the living room for a while, but always on his phone, the corner of his mouth lifting every so often.

He used to bring me a gift when he came back from a business trip. It was always a hand cream set from the airport duty-free, but at least there was something.

Now there wasn't even hand cream.

He used to speak to me in a tone that was neither warm nor cold.

Now he spoke to me with impatience.

As if my very presence in this home were an interruption to him.

I checked his phone bill.

We had a family share plan, and the bill came to my email every month.

There was one number he'd been calling frequently over the past three months. Every day, sometimes four or five times a day. The calls weren't long, but they were constant.

I looked the number up. The profile picture on the messaging app was a white cat.

I'd seen that cat before.

In Agatha Pruitt's posts.

Agatha Pruitt, Brad's junior from college, now in the same industry, the two companies doing business together.

When Brad used to mention her, his tone was as flat as if he were talking about any ordinary coworker.

"Agatha? Oh, she was in our college drama club. She played the lead back then, and I directed her in a few scenes."

"Interesting person. Says what she thinks, doesn't hide things, not like all those girls out there who play games."

"She just got promoted to director. Pretty impressive. That personality of hers really is suited for marketing."

I didn't think much of it at the time.

Looking back now, the admiration in those words had spilled over long ago.

I was just too foolish to hear it.

That day was a Saturday.

Brad was home for once, but he changed his clothes first thing in the morning and stood in front of the mirror for a long while.

He never looked in the mirror before going out.

"Where are you headed?"

I asked him.

"The office. There's a project to discuss."

"But it's Saturday."

"You wouldn't know, since you don't work. Projects don't take weekends off."

Brad was getting impatient.

He picked up the car keys and walked to the door, then suddenly stopped and glanced back at me.

It was a strange look, as if he were hesitating over whether to say something.

But in the end he said nothing and left, the door closing behind him.

I stood on the balcony and watched his car pull out of the complex.

Then I did something I'd never done before.

I called for a ride and followed him.

His car didn't go to the office. It drove to an upscale complex on the east side of the city.

He parked in a surface spot, then pulled a bouquet out of the trunk.

Pink roses.

The wrapping was elegant, the kind you could tell had been ordered in advance.

Cradling the flowers, he walked into one of the buildings.

I got out of my ride at the complex gate, walked over to the foot of that building, and tipped my head back, counting the floors.

He stopped on the ninth.

I stood down there, I don't know how long.

The sun was harsh. I didn't have an umbrella, and my skin burned under it, but I couldn't feel a thing.

There was only one thought in my head: the flowers he gave someone else were carefully chosen pink roses.

But the ones he bought me were always the supermarket lilies, three for ten dollars, thrown together however, like he'd grabbed them on his way past.

So it turned out Brad Fox did know how to pick flowers, did know what romance was, did remember the dates.

He just didn't want to do any of it for me.

I took out my phone, snapped a photo of that building, and left.

Back home, my son was in the living room watching TV.

He was four this year, in the middle class at preschool.

When he saw me come in, he ran over and wrapped his arms around my leg.

"Mommy, where did you go? I was all alone and so scared."

That was when I remembered he'd been asleep when I left, and I'd forgotten to tell him.

I crouched down and held him.

"I'm sorry. Mommy stepped out for a bit. It won't happen again."

He touched my face.

"Mommy, were you crying?"

"No. Mommy just got something in her eye."

I wasn't crying.

I couldn't.

I just kept asking myself, what exactly had I done wrong?

Every morning I got up early to make his breakfast, every night I waited for him to come home, every time he was sick I stayed up all night caring for him, every time he hit a wall I was the first to stand behind him.

I gave up my own dreams, gave up my own circle of friends, gave up the best years a woman has.

And what I got in return was him delivering flowers at another woman's door.

Was it that I hadn't been good enough?

Or had I never been the person he wanted?

That night, Brad came home at eight.

Earlier than usual.

When he walked in, his hands were empty.

No flowers, no gift, not even an "I'm home."

He changed his shoes, washed his hands, sat down at the table.

I'd made his favorite dishes. He ate for twelve minutes and checked his phone five times.

I sat across from him and didn't touch a bite.

When he finished, he set down his chopsticks and finally glanced at me.

"Why aren't you eating?"

I managed a small smile.

"I'm not hungry yet."

So he didn't ask again, just got up and went to the study.

While I was clearing the dishes, I saw the phone he'd left on the table.

The screen lit up.

A text message.

"Brad, the flowers today were so pretty, thank you. When I get back from my trip next week, can you still come pick me up?" followed by a sticker of a kitten pawing for attention.

Sender: Agatha Pruitt.

I looked at that message, my hands shaking.

Not from anger. Because I finally knew for certain.

Certain that I hadn't been imagining things.

Certain that it wasn't that I wasn't good enough, but that there really was a third person in this marriage.

I set the phone back where it had been and went on washing dishes.

The water ran loud from the faucet, drowning out every other sound.

Including the sound of my heart breaking.

I didn't lay it all out right away.

I needed time to think through what it was I actually wanted.

Did I want a divorce?

Did I want to save it?

Did I want to keep pretending I didn't know?

Every option was hard.

My son was only four, and my parents were back home, in poor health. I couldn't let them worry.

My own career had only just started to take off. If I divorced him, raising a child alone, the financial strain would be brutal.

But more than that, I couldn't stand it.

I couldn't stand handing over five years of marriage to a woman Brad described as lively, sunny, and free of pretense.

I'd met Agatha Pruitt a few times.

Every time, she was dressed to the last detail, her makeup flawless, her voice pitched just so, every word like it had been rehearsed.

In front of Brad, she always wore the same look: I don't understand any of this, so come teach me.

"Brad, can you take a look at this proposal for me, pretty please?"

"Brad, that theory you mentioned last time was so deep. Explain it to me again?"

"Brad, you're too good to me. I don't even know how to repay you."

Soft, coaxing, every sentence trailing up at the end, every word with a hook in it.

I used to think that was just her personality. Now I understood it wasn't personality at all. It was a tactic.

And Brad ate it up.

To him, that was lively and sunny and unpretentious.

That was being genuine.

That was holding nothing back.

And me?

I was the one who was too serious, too earnest, who didn't know how to put a man at ease.

I handled everything that actually mattered, and he found me dull.

She didn't have to do a thing. She just had to play cute, and he thought she was wonderful.

I don't know if that counts as irony, but I did find it funny.

Funny enough to make me want to cry.

Before I could even decide what to do, the news came that our son's preschool was holding a parent-child sports day over the weekend.

It required both parents to attend.

I also wanted to use it as a chance to thaw things between us a little.

I told Brad. He just frowned and said, "I've got something that day."

"What something?"

"I leave for a business trip Friday night."

"The sports day is Saturday morning. Can't you leave Saturday morning instead?"

He shot me a look. I knew that look. It was impatience.

"Hope, I told you I have something. It's a preschool sports day. You can go by yourself. There's no need for both of us to be there."

I didn't waste any more words trying to argue with him.

But I quietly checked his schedule.

It took me less than an hour to find out: Friday night, Brad wasn't going on any business trip.

His car was parked in a spot at that complex on the east side of the city.

It stayed there until the early hours of Saturday before it left.

Saturday morning, I took our son to the sports day alone.

Every other kid had both a mom and a dad. Our son stood alone beside me, looking up at me, and said quietly, "Mom, where's Dad?"

"Dad's away on a business trip."

He went quiet for a moment, and when he spoke again there was a sob in his voice.

"Mom, does Dad not like me?"

I crouched down and looked him in the eyes.

"It's not that he doesn't like you. Dad's just very busy."

He was still hiccuping through his tears.

"But Cody's dad is busy too, and he came today."

I didn't know what to say. All I could do was scoop him up.

"Mommy likes you. Mommy will always like you."

When the sports day ended, there was an activity called "A Gift for Mom and Dad."

Aaron made a card. On it he'd drawn three people: Dad, Mom, and him.

Beside Dad's head, he'd drawn a big question mark.

The teacher said, "Aaron, why did you draw a question mark?"

He tilted his head up. "Because Dad's always so busy. I can't remember what Dad looks like."

I held that card, my hands trembling.

That night, Brad came home a little after nine.
