My Fianceé Demanded An Open Marriage To Cheat But Didn't Expect My Revenge

The next few days were a psychological chess match. Chloe tried every manipulative tactic in the book to "close" the door she had forced open. She’d "accidentally" leave her phone open to photos of her and this guy—let’s call him Marcus—hoping to get a reaction. I gave her nothing but a polite nod.

The more I didn't care, the more she spiraled.

By Tuesday, I had my second date lined up. A school teacher named Sarah. When I told Chloe I wouldn’t be home for dinner because I was seeing Sarah, she finally cracked.

"You’re doing this to punish me!" she screamed, throwing a throw pillow at the wall. "You’re rubbing these women in my face!"

"Chloe," I said, my voice like ice. "You gave me an ultimatum. You told me you needed this to be fulfilled. I’m simply respecting your boundaries. Why are you upset that I’m being a supportive partner?"

"It’s not supposed to be like this! You’re supposed to fight for me! You’re supposed to tell me I’m enough!"

"I did that for four years," I replied. "You told me it was archaic. Now, if you’ll excuse me, I have a reservation."

The next morning, I woke up to a sound I didn't expect: multiple voices in my kitchen. I walked downstairs to find a full-blown "intervention." Chloe was huddled on a chair, looking pale and fragile. Sitting around my kitchen table were her mother, her older sister, and her best friend, Sarah (not the date Sarah, the 'loyal' best friend Sarah).

"Good morning, everyone," I said, heading straight for the coffee maker. "I didn't realize we were hosting a summit today."

"Ethan, sit down," her mother snapped. She was a woman who lived for drama and had always looked down on me for being 'too cold.' "We need to talk about your behavior. Chloe is a wreck."

"She’s barely eating, Ethan," her sister added, glaring at me. "How can you be so cruel? Going out with other women while you're engaged to my sister? Have you no shame?"

I poured my coffee and leaned against the counter. "Did Chloe tell you whose idea the open relationship was?"

Silence. Chloe looked at the floor.

"She said you forced her into it because you were 'bored' and wanted to cheat with a clean conscience," her best friend spat. "She said she only agreed to save the wedding."

I actually laughed. It was a sharp, dry sound. "Is that the story, Chloe? That I, the man who spent two years paying for your car note and your master’s degree, suddenly decided to 'force' you into an open relationship?"

"You're twisting things!" Chloe sobbed, burying her face in her hands.

"Ethan," her mother said, standing up. "This ends now. You will apologize, you will delete those disgusting apps, and you will move into a hotel for a week to give Chloe some space in her home to heal."

I stopped smiling. "Her home?" I stepped forward. "I bought this house in 2022. Chloe’s name isn't on the deed, the mortgage, or even the utility bills. This is my home. And as for the hotel... I think you’ve all stayed long enough."

"You can't kick us out!" her sister yelled. "We're family!"

"We were going to be family," I corrected. "But family doesn't walk into a man’s house and tell him to leave based on a web of lies. You have five minutes to leave my property before I call the police for trespassing. Chloe, you can stay—for now—but your guests are gone."

They left, huffing and throwing insults about how I was "abusing" her. Once the door clicked shut, Chloe turned on me, her victim mask slipping.

"You think you’re so smart, don't you? You think you can just throw me away?"

"I’m not throwing you away, Chloe. I’m observing you. Tell me, who is Marcus? Is he the one who took you to the steakhouse on Friday? The one you've been 'growth-searching' with for the last four months?"

Her face went bone-white. The name 'Marcus' was the key that unlocked the vault.

"How... how do you know his name?"

"I'm a project manager, Chloe. I notice details. I also notice that you haven't been 'wedding planning.' You've been 'exit-strategy planning.' So here’s the new deal: you stay in the guest room. I stay in the master. We are 'open,' remember? And tonight, I’m going on my third date."

She looked at me with pure hatred. "If you walk out that door tonight, we are finished. The engagement is over."

I reached into my pocket, pulled out my phone, and checked the time. "That works for me. But you might want to check your email before you make any more threats. I just sent a little something to your father that he might find... enlightening."

The look of sheer terror on her face told me I had hit a nerve I didn't even know existed yet...
