I know I'm not alone in this. The divorce rate these days are so high, I do even have the slightest inkling to get married. People seem programmed to the point where they think they have to do it. I think it's fine if people are married, but it doesn't mean what it should anymore. What does everyone else think?
I used to be one of those people who thought that marriage was a prison, and that it would be too confining. The older I get though, the more I realize that marriage is not only a wonderful thing, but it is almost necessary...so long as one plans on starting a family one day. And while fewer and fewer people are having children, at least in first-world countries, children will be made, and they will need to be taken into consideration.
If you do not plan on having children, and choose to either date various people until you die, or stay with one partner with no children involved, I see no problem with not getting married.
On the other hand; If you plan on having children and raising a family, you better make it for life. No one can ever be certain that things will remain the same and the bond will remain intact. Partners have been known to grow a disliking for one another, and adultery has been known to occur. Yet, it is in the best interest of not only your children, but your society as well, to keep your family intact. The world needs less screwed up people, and divorce has a major impact on children, especially when they are young.
I think it's important to remember the following: What one does, does not only affect themselves, but everyone around them. We are all linked together, and if we take the approach of taking care of our own business, everyone gains as a result.
