All the divorce statistics mean is that there's a bunch of people getting married who shouldn't. It also shows that today's society places alot more importance on career and independence than family.
In my mind, getting married means you make sacrifices of yourself, your choices, and your time to make the relationship work. If you've chosen well the other person will too; and whatever the future brings, you'll face it together as a team. That doesn't mean.. hey I want to do X, but if I do it I won't be able to stay with my SO.. oh well, guess it wasn't meant to be, BYE!
Too many people do not take marriage as an actual commitment, they take it as a convenience or something they were supposed to do. Thats why the divorce statistics are what they are. If you're not ready to make that sacrifice, of course you shouldn't get married - do yourself a favor!
