Narcissism is when a person has an inflated view of themselves. In the book, Narcissism Epidemic: Living in the Age of Entitlement, the incendiary problem is learned at a young age when children are taught to put themselves first and are instructed that they are at the center of the universe. This message is repeated throughout their lives by the media and social media. "It's the message preached by prosperity gospel and the vacuous ethos spread by celebrity newsmakers. And it's what's making people depressed, lonely and buried under piles of debt," researchers Jean M. Twenge and W. Keith Campbell wrote. The belief that it's "all about me" filters into other parts of our lives. It makes sense that these messages and self-centered views permeate relationships. If you are married to a narcissist, here is a look at how to manage their behavior.
