What is your idea of a relationship?

Is a relationship just a status for some people? I believe relationships need real hard work and a lot of time put into them. I don't believe people put that time in any more with the pressures of modern life. Is it any wonder the divorce rate is so high? How do you long term successful couples survive? Am I right in saying it's because you will do ANYTHING for each other? Am I right you are always there for each other no matter what? Let me know your opinions people
