How to Know if it's True Love

How do you know when you really love someone? While many people still marry, others do not. They live together in a state of cohabitation and develop relationships that may or may not last. At one time the word infatuation was used to refer to those who fell in love with someone rather quickly. People were told that they couldn't possibly love someone that they hardly knew. But then many people believe in love at first sight and some relationships of this type have lasted many, many years.
