I saw her today. Not sure if she saw me.
She was leaving the campus parking lot. I was parallel parking on the street opposite the campus.

I've been thinking about apologizing to her husband, but had to stop myself and have this inner dialogue: "What's done is done, no amount of guilt felt or sorrow conferred will negate the actions rendered. Stop dwelling! Move forward, it is not as important as you would like to make it."

Done.
