A few months after my husband moved out of the house, I was trying to calm and reassure Rhett, then six years old, at bedtime. He said, “I know, I know. I have a mom who loves me, and I have a dad who loves me. But I don’t have a family.” I felt the wind go out of me—felt myself emptying, falling, a balloon drifting down from the ceiling—because he was right. He still had all of his family members, but our family unit, our foursome, was gone.
