My Dad Invited My Brother and Me to His Wedding to the Woman He Cheated on Our Mom With – He Had No Idea He’d Regret It Soon

When my dad invited my 12-year-old brother and me to his wedding, I thought the hardest part would be watching him marry the woman who destroyed our family. I had no idea my quiet little brother had his own plan.

I’m Tessa, 25 now. My brother Owen used to be the gentlest kid—drawing cards for Mom, crying over cartoons. After Dad’s affair and divorce, that softness changed. Dad left Mom after 22 years for Dana, his coworker, and moved in with her within weeks. Mom fell apart quietly while Owen kept asking one question we couldn’t answer: Why didn’t Dad want us anymore?

A year later, Dad announced his wedding and insisted we attend. Family pressure wore Owen down, though something about his calm worried me. Two weeks before the ceremony, he asked me to order itching powder online. I didn’t stop him.

At the wedding, Owen politely offered to hang up Dana’s white jacket. Minutes into the ceremony, Dana began scratching. By the vows, her skin was red and burning. She fled the altar, reappearing later in a wrinkled dress, embarrassed and shaken. The ceremony resumed, but the moment was ruined.

That night, Owen said quietly, “She didn’t cry like Mom did. But she’ll remember how it felt.”

Now Dad won’t speak to us. The family demands an apology. I haven’t given one.

I didn’t plan it—but I don’t regret not stopping it either.

Am I wrong? I don’t know. But I’m not sorry.
