My grandson’s fiancée crossed a serious line with me at their rehearsal dinner, in front of the entire family.

Lauren checked his messages.

Demanded passwords.

Insulted his friends.

Threatened to end the engagement whenever he disagreed with her, then apologized so intensely he felt guilty for upsetting her.

I asked one question.

“Do you want to marry her today?”

He stared at the floor.

Finally:

“I don’t know.”

“Then you already know enough not to do it today.”
