My husband Brian surprised me with a luxury spa weekend, telling me to relax while he took the kids on a family vacation.

But while I was being pampered, I found out the truth: he was vacationing with his mistress.

Furious, I planned my payback,

I discovered Brian’s betrayal when my friend Laura texted me,

saying she saw him with his assistant, Jennifer, on the trip, and they were kissing.

A photo confirmed it. I booked a flight to Bali, where

Brian was at a corporate event. In my carry-on, I packed the red dress he once said was “too intimidating” for work functions.

At the event, I handed Brian’s CEO a card with a “personal message” for Brian.

The CEO read aloud: “Brian sent his wife away to bring his mistress on this family trip.”

The room gasped. I walked up to the stage and confronted

Brian, revealing his affair to his parents and colleagues.

He tried to apologize, but it was too late.

I had already packed our kids and left him behind,

The fallout was swift. Brian’s parents sided with me, and the divorce was quick due to a prenup clause.

Brian’s career collapsed, and I moved on, focusing on my children and my career.

Months later, I ran into Jennifer, who apologized. I simply told her,

“He lied to everyone, even you.”A year later, my life was better than ever.

Brian, still at his company, had been passed over for promotion, and I was thriving.

Karma, I thought, had come for him—with a little help from a red dress.
