First off, let’s begin with a disclaimer. This piece is not here to encourage anyone to cheat on their spouse or anyone they are in a relationship with right now. Let’s just put that out there to begin. However, history is filled with plenty of salacious affairs where people stepped out of their relationships and some people got away with it for years through tenacity and cleverness. So, if you’re planning on having an affair or you’re already playing on the side (stop that!) perhaps history can give you a guide on how to have a proper affair (which you should absolutely not do!).
