My teenage daughter's stepfather regularly took her out for ice cream late at night – When I watched the dashcam footage, I had to sit down

"Because you don't want me to be happy!"

Vivian stood up abruptly. "Every time I want something, you tell me I have to focus on school, study harder, do better... You treat me like I'm a machine!"

I felt like my breath had been taken away.

"Why do you think that?"

"All you care about is my average," Vivian continued. "I'm just a schedule to you."

"It's not..."

"That's true!" Her eyes filled with tears.

"You just want me to keep going until I break down."

Mike went over to her, and she burst into tears when he hugged her. I wanted to argue, but all I could think about were the nights I'd sat at the table while she studied, pushing her to work harder, to study more... What had I done wrong?
