Does being married determine whether your relationship will stay up or come crashing down?

I don't get why women expect things to be at an all time high through out their marriage...few months in they call it boring...Why allow a piece of paper to change the aspects of your relationship?? Ive never been married and would like some insight on some marriages...every woman I know has gotten a divorce...I want that forever marriage...Im just wondering...What are your thoughts on marriage? And if you've been married for 10+ years kuddos and congrats!
