Sadly most people are not. People get into relationships for all of the wrong reasons with the wrong people. However, because people want what they want they will get into relationships they shouldn't be in. There are many people who are married to people they're not evenly yoked with and people who aren't really meant for them. This is what happens when individuals chase after the flesh (desires, wants, feelings, emotions, self gratification, the superficial, etc). They ultimately end up in unhappy unfulfilled realtionships.
