The story goes that in Europe during the war, Eisenhower had an affair and was serious enough about it to tell his superior that he was planning to get a divorce so he could marry her. It was his superior who told him he'd halt his career cold if he dis something so rash.

Soldiers, prospectors, prisoners- I don't blame any of them if they don't stay 'true' to their loved one at home. That really is one time when it has nothing to do with her. IMO
