The week before my wedding turned into a nightmare when I walked into my kitchen to find 200 hand-calligraphed invitations shredded—and my younger sister, Katie, standing there with scissors. What started as confusion turned into shock when she revealed why: my fiancé, Daniel, was having an affair with my dad’s girlfriend, Susan. At first, I didn’t believe her—until she showed me a video of them kissing and discussing how Daniel would inherit my dad’s cottage after we married. I felt devastated… until the heartbreak turned to fury.

With Katie’s help, I decided to expose them on what was supposed to be my wedding day. As guests gathered and Daniel stood at the altar, I paused the ceremony and played a slideshow of their affair—video, texts, voicemails. The crowd gasped, my dad stormed out after Susan, and I called off the wedding then and there. I left the venue to applause and support from friends and family. Daniel disappeared from my life, and Susan from my dad’s. And Katie? She’s now my hero—and future maid of honor, whenever the right person comes along.
