The package arrived before breakfast on the morning of my ex-husband’s wedding. My seven-year-old son Eli ran to the door when he saw his father’s name on the box, hoping it meant Mark still cared about him. Inside was only a broken old toy car with no note.

I watched the excitement disappear from my son’s face as he whispered, “Is this it?” Then Mark sent a message saying something I never expected from a father. That night, after seeing my son hurt, I broke the toy apart—and something hidden inside changed everything.
