I discovered my husband was cheating on me with my own sister while I was pregnant — so at our gender reveal party, I prepared a special “surprise” for him. I was expecting my first child. Blake and I had been married for eight years. He had seemed charming, attentive, and caring — everything I had wanted. When I told him I was pregnant, he hugged me and cried with happiness. A big gender reveal party was planned, and both sides of the family were invited. The backyard was covered in pink-and-blue lanterns, ribbons, and decorated tables. The centerpiece was a giant box meant to release either blue or pink balloons so everyone could learn the baby’s gender. My sister, Harper, had ordered the box because the doctor had told her the baby’s gender alone.
Two days before the party, Blake was in the shower while I rested on the couch. A phone began to vibrate. I picked it up, assuming it was mine — but it was his. A message appeared from “
“: “Can’t wait to see you again. 
Same time tomorrow, sweetheart 
.” My blood went cold. My hands trembled as I opened the chat… and everything fell apart. Flirting. Secret meetings. Photos. In one of the photos, I realized who “” was. It was my sister, Harper. My own sister. I nearly fainted from the shock. It felt as if the ground had vanished beneath me.
For a moment, confronting them both and saying everything I felt seemed possible — but it was not enough. So I pretended I knew nothing and made MY OWN PLAN. The next day, the event organizers were called, and a few key details of the party were changed. When the gender reveal began, guests gathered around Blake and me, full of anticipation. Then the lid of the box was lifted. A hush fell over the group, and I could see shock on everyone’s faces. BECAUSE INSIDE, THERE WERE NO PINK OR BLUE BALLOONS.
