Relationships are impossible, or are they. Why is it that most relationships dont work. Man meets woman, they date, move in together, get married, have kids and then divorce. This is what most relationships are nowadays. What causes a relationship to fall apart, what relationships you should get out of and are there such things as soul mates. Most people believe that their relationship isn't like others. They don’t have problems. These kinds of people also think that their partner wont cheat on them or do anything wrong.
