We’ve been married two years, and every first Saturday of the month, my husband vanishes for a few hours. ‘Running errands,’ he says, or ‘Helping my aunt.’ I never questioned it—he’d come home with groceries or a bakery bag. But last month, I asked to tag along. His face tensed. ‘You know my aunt doesn’t really like you, so it’s better you don’t come,’ he muttered before driving off. I barely spoke to his aunt but never felt any hostility.

So this month, I tucked a GPS tracker under his car and followed him.He drove 30 minutes out of town to a run-down house and rushed inside. I knocked. The tears appeared in my eyes when the door opened and I saw a woman holding a baby who looked just like my husband.My heart dropped into my stomach. She looked startled to see me. “Can I help you?” she asked quietly, shifting the baby on her hip. I just stared at the baby’s dark eyes, identical to my husband’s. I tried to breathe. My voice cracked when I finally found the words. “I’m his wife. Who are you?”
