Discovering that your significant other is messing around with someone else behind your back sucks. The silver lining is that at least you found out about it now rather than later. In Marina Voinova’s case, it was her fiance (now ex-fiance) who did some canoodling with some unknown, random chick. What makes her case different is that she didn’t find out by snooping around or walking in on them or something.
Instead, she found out on the Russian version of Google Maps called Yandex Maps.
