College professors! Yep! My ex, AKA "Professor Playboy" definitely was having inappropriate relationships, meetings, "glasses of wine", etc. with his students during most of our 21 year marriage.
He also had a very irregular schedule that involved lots of driving to different campuses. I never knew when to expect him home for dinner, but at the time all of that was brushed aside as either traffic or staff meetings.
