My Sister Slept With My Husband While I Babysat Her Kids,

People always said I was too nice. Too forgiving.
They were right—until the night I realized my sister was sleeping with my husband while I babysat her kids.

After our wedding, Jack slowly disappeared from our marriage. No walks. No dinners. Just his phone and his indifference. That night, when I tried to talk, he barely looked up.

Then my sister Linda called, begging me to babysit—again. I agreed, like I always did.

Hours passed. No texts. No explanation.

At two in the morning, I realized I’d forgotten my inhaler. Panicking, I asked the neighbor to watch the kids and rushed home.

Linda’s car was in my driveway.

Inside, I followed laughter upstairs. Clothes littered the stairs. I opened the bathroom door and found Jack in the tub with my sister, wine glass in hand. Rose petals covered my bed.

That was the moment I stopped being kind.

The next morning, I returned to Linda’s and took a strand of hair from her youngest son, Tommy. I already suspected the truth—he didn’t belong to her ex… or to Jack.

Two weeks later, the DNA confirmed it: a partial match. Enough to destroy lies.

By then, Jack had left me for Linda.

So I paid them a visit.

When I revealed the results, Linda finally snapped and admitted the truth—Tommy was Jack’s brother’s child. She’d been taking hush money for years.

Jack was sickened. Furious. Betrayed.

I stood, calm and smiling.
“Looks like you picked the wrong sister.”

Then I took the kids for ice cream and walked away while their perfect house collapsed behind me.

That day, I chose myself.

And revenge had never tasted so sweet.
