My husband Jack’s best friend Megan, who was like a sister to him, had been part of our lives for years—but my patience with her ran out. She always inserted herself into our family gatherings with a smug smile, and Jack dismissed my concerns as insecurity.

Two months ago, Jack started coming home late and acting secretive. When I finally checked his phone, I found intimate, flirtatious messages between him and Megan. They’d been having an affair for months.

At a family BBQ, tensions exploded. Jack’s dad Rick arrogantly defended Megan, calling my feelings insecurity. Then Jack’s mom Nancy dropped a bombshell: Rick had been cheating on her with Megan too.

Nancy kicked Rick out and filed for divorce. I left Jack, refusing to stay for the kids after his betrayal. I exposed Megan online, revealing her affair with both Jack and Rick. Megan lost everything—her job, reputation, and place in the family.

It was painful, but I stood my ground. Megan destroyed my marriage; I destroyed her lies.
