There are often couples seen in public that are perfectly compatible. Even when they are not together in the morning, their clothes somehow match. They are able to finish each others' sentences when they speak. They have the same code of ethics and the same goals in life. It almost seems as if neither one of them can function without the other. These couples often claim they are two halves of one soul.

Many people envy these couples and their happiness. Other people look closely and wonder if they are truly content with each other. Too much of a good thing is not always best, and this applies to relationships. While many of these couples live their entire lives together, some of them suddenly wake up one morning as unhappy people. They leave their partner behind in a welter of confusion and pain because they no longer want to see themselves when they look at their significant other.
