It happens, and it happens a lot because people marry the wrong person, married on a whimp, married on social pressure, or they plain and simple changed (or didn't).
This is life and this is human nature. You marry with both eyes open, and after that you keep one closed if you want it to last.
A friend once told me that guys marry the woman hoping she doesn't change, and women marry men hoping they will. There in lies the root of disappointed expectations and inevitable failure in marriage.
But who am I to speak. I'm not married. I'm not close to it and I certainly am not going to.
What's with marriage anyway? It's like marking your territory in the eyes of the law. What has the law to do with my personal life? As it is it's invaded enough of my personal space. It's unnecessary pressure to make sure the relationship works, otherwise there will be FINANCIAL penalties, as if the emotional ones are not enough.
In the past I can understand why the law had to step in because women were financially dependent on men. But we live in different times. In fact I know of many women who use the law to milk their ex-husbands for money.
This of course is not to say there aren't genuine cases. But seriously, if you want to be with the person, then be. Why let something that's meant to be between 2 people, become the State's business...and for the unfortunate Woods and Jack, it's now the whole damn world's business.
Give 'em a break. There are bigger things happening in this world.
