After Divorce, I Took Revenge on my Ex-husband and His Mistress

On my thirtieth birthday, my husband slapped me hard. "Did you ever study biology in high school?"

he yelled. "You have type O blood, I have type B. So how on earth does our son have type A blood?"

I was completely stunned. Could our child have been switched at birth?

But in court, I calmly showed the paternity test results proving he was indeed the father.

My husband was left speechless.

Watching him walk out of the building, I felt a strange sense of satisfaction.
