I slept with my ex-wife again during a business trip, and in the early hours of the morning, a red stain on the sheet took my breath away. A month later, a call from a hospital in Cancún made me realize that that night hadn't been a mistake… but the beginning of something much darker.

 I slept with my ex-wife again during a business trip, and in the early hours of the morning, a red stain on the sheet took my breath away. A month later, a call from a hospital in Cancún made me realize that that night hadn't been a mistake… but the beginning of something much darker.

It's still hard for me to talk about it without getting a lump in my throat.

I hadn't seen Elena in almost three years, since the divorce. We hadn't separated because of infidelity or a scandal. Our relationship had faded little by little, between meetings, exhaustion, pointless arguments, and increasingly long silences. One day, we signed the papers, shook hands almost like strangers, and went our separate ways.

I stayed in Mexico City, immersed in a construction company. Elena went to Quintana Roo to work in the hotel industry. I heard about her through mutual friends, nothing more. That she was doing well. That she seemed calmer. That she almost never spoke about her past. And I didn't ask her any questions either.

Until they sent me to Cancún for work.

The idea was to inspect a plot of land for a new hotel complex and return to the capital two days later. I arrived tired, checked into a hotel in the hotel zone, and that night went for a walk to clear my head. Music drifted from the bars, tourists were taking pictures, the humid air clung to my shirt.

I went into a small, unassuming bar, one of those dimly lit places where you just go to sit for a while. I ordered a beer. And when I looked up, I saw her.

Elena was at the bar.

I don't know how to explain it, but even with her back to me, I recognized her instantly. The way she styled her hair, the way she held her glass, that serious posture she always adopted when she was lost in thought. I felt a jolt in my solar plexus. When she turned around and saw me, her eyes widened, as surprised as I was.

“Carlos?”

I don’t know how long we stared at each other, but it was strange. As if those three years had suddenly vanished. We ended up sitting at the same table. At first, we spoke cautiously, like two people who know each other too well and, at the same time, barely recognize each other. She asked me about my job. I did the same. We laughed about an old trip to Puebla, about a silly argument over a dog we never adopted, about things that, in the past, would have been more hurtful.

The worst part was realizing that I could still talk to her naturally. Like before.

Around midnight, she told me she knew the hotel where I was staying. Then she suggested we take a walk on the beach. And I, who had spent years convincing myself that I had forgotten her, agreed like an idiot.

The beach was almost deserted. The sea roared loudly, but not as loudly as everything that was churning inside me. We walked barefoot on the sand, talking about this and that, about memories, about how we'd ruined everything. At one point, Elena fell silent and simply looked at me.

That was enough.

That night, she came back to the hotel with me. I didn't think much of it. I wanted to believe it was a strange goodbye, a shared weakness, something that would stay buried in Cancún. We didn't even talk about the "next day." It just happened, that's all.

But at dawn, everything changed.

I woke up late, the sun filtering through the curtains. Elena was already by the window, holding one of my shirts. For a second, I felt something dangerous: peace. That kind of peace that makes you forget why a relationship ended.

Until I got out of bed. And saw the sheet.

There was a red stain.

It wasn't big. But it was there. Clear. Impossible to ignore.

I froze. Elena turned, saw my face, and for a second, I could have sworn she was scared too. She rushed to the bed, pulled back the sheet, and said, too quickly, that it was nothing, that I shouldn't ask questions, and that I should take a shower because I had work to do.

It wasn't the response of someone who was calm. It was the response of someone who was hiding something.

That morning I stayed in the shower longer than necessary. The water cascaded down my neck, but I couldn't silence that strange feeling that had settled in my stomach. Something was wrong.

When I came back out, Elena was already dressed.

The sheet was gone.

The room smelled of perfume and cold coffee.

She avoided my gaze.

"Elena…"

"Don't start, Carlos."

"Then explain it to me."

She closed her eyes for a second, like someone trying to hold back a heavy truth.

"This shouldn't have happened."

"What is it?"

She looked at me, and I saw something in her eyes I hadn't seen before. Fear. Not fear of me. Fear of what was to come.

"I have to go."

She grabbed her purse, gave me a quick kiss on the cheek as if she were putting a band-aid on a deep wound, and then left.

I stayed there, alone in that hotel room, with the missing sheet and the feeling that that night had been more than just a simple mistake.

In the following weeks, I tried to get my life back on track.

The construction project.

The meetings.

The phone calls.

But Elena was always on my mind.

I wrote to her twice. I didn't get a response.

I finally convinced myself that she was simply sorry for what had happened.

A month later, my phone rang.

Unknown number.

Cancun area code.

I barely answered.

"Mr. Carlos Ortega?"

"Yes."

"This is the Cancun General Hospital. Elena Salazar added you to her emergency contact list."

My blood ran cold.

"What's happening?"

There was silence.

Then a deeper voice.

"Her condition is critical."

I barely remember the trip to the airport. Only my hands were shaking so much I couldn't close my suitcase. Only that feeling of falling into the void during the entire flight.

When I arrived at the hospital, Elena was connected to several machines.

Her face was pale.

Too pale.

Her lips were dry.

She closed her eyes.

Beside her bed was an older woman who stood up as soon as she saw me.

Her mother.

She had aged ten years since the last time.

She stared at me for a long time.

Then she began to cry.

"She didn't want to call you."

"Why would I?"

The woman clasped her hands.

"Because she didn't think she had the right."

I watched Elena.

Then her mother took a crumpled envelope from her purse.

"She wrote it just in case."

My fingers trembled as I opened the letter.

“Carlos,

If you’re reading this, it means something went wrong.

I wanted to tell you the truth that night. I swear I wanted to tell you.

The blood on the sheet wasn’t what you thought.

Three weeks before I saw you again, I found out I was sick.

Cervical cancer.

It’s quite advanced.

The doctors told me I needed surgery urgently. Very urgently. But I couldn’t. I didn’t have enough money. And, above all… I didn’t have the strength anymore.

When I saw you in that bar, I remembered what it felt like to be alive. I just wanted one last night where I wasn’t a sick woman, a lonely woman, someone waiting for the end.

I wanted to be Elena one last time.

I’m sorry I hid the truth from you.

And there’s something else.

I never left because I didn’t love you anymore.

I left because I couldn’t bear to see what we had become.

I still loved you too much to Stay.

Elena.

I don't know how long I sat there, unable to breathe properly.

When I finally looked up, her mother was crying silently.

"Why didn't she tell me anything?" I asked.

"Because she knew you would have given up everything for her."

I sat down near the bed.

I took her hand.

She was cold.

Fragile.

As if life itself had abandoned her long ago.

Then, gently, her fingers moved.

She barely opened her eyes.

She looked at me.

And despite the machines, despite the pain, despite everything that had separated us, she recognized me immediately.

"Carlos..."

I leaned toward her.

"I'm here."

She closed her eyes for a second.

A tear rolled down her cheek.

"I didn't want you to see me like this."

I felt such a strong lump in my throat that I thought I was going to suffocate.

"Look at me closely, Elena."

She opened her eyes again.

"I'm still here."

She tried to smile.

A small, broken smile.

"You're always late," she murmured weakly.

I laughed through my tears.

Because she was right.

I arrived too late to realize she was suffering.

I arrived too late to see her slipping away.

It's too late to realize you can still love someone even after a divorce.

But this time I wasn't late.

This time, I was there.

And for the next three weeks, I never left her side.

I slept on a couch.

I held her hand.

I told her silly stories.

I told her about the dog we never adopted.

About the trip to Puebla.

About everything we had lost.

And one morning, just before dawn, as the sky turned to Blue beyond the hospital windows, Elena placed her hand on my cheek.

"Thank you... for coming back."

Then she left.

And since that day, every time I think of that red stain on the sheet, I no longer think of the shock.

I think of the fact that she already knew she was going to disappear.

And that, in the midst of that fear, in the midst of that impending end, she had wanted to spend one last night remembering what it felt like to be loved.
