Growing up, I didn’t know my biological dad, and my mom married my stepdad when I was 4 so I remember little before him. They had a fine marriage, but there were always issues. Even as a kid I was aware of that. Money, church, friends, attitudes, other attractions, the chore of children … these things weighed on my parents. There were times I thought their marriage was over, but then they’d come back together again—until the time they didn’t.
