Couples must avoid this one thing if they want to stay happy

It's been ten years since the release of Neil Strauss' bestselling book "The Game: Penetrating the Secret Society of Pickup Artists." Now the author has a new book called "The Truth: An Uncomfortable Book About Relationships." 

Strauss stopped by Business Insider to talk about what he's learned since the success of "The Game," and in the process he revealed a fascinating perspective on the reason people cheat on their significant others.
