When the DNA results arrived, no one in the room could breathe. My husband, Adrian Villareal, stared at one line on the  paper. Bianca Reyes, my best friend who had just given birth, turned pale. And for the first time in three years, I smiled.

Seven days earlier, on our wedding anniversary, I blocked the doorway of a private hospital delivery room in Makati. Inside, Bianca lay in bed with the baby Adrian proudly called his son. When the nurse asked for the father’s name on the birth certificate, I took the clipboard and said, “Wait. Let’s do a DNA test first.”
