I've been married for 16 years now and I was blissfully happy 10 of those years. But, marriage has it's ups and downs. Some times are great and some times just suck. Sometimes you can't imagine life without your spouse, sometimes you can't imagine staying there one more day. No one is happy all of the time. People drift a part, but it's important to try to drift back together. If you let yourself drift apart too long.....

Most people I know have been divorced at least once. (I haven't) I've heard some people say (who have gone through multiple divorces) that if they knew then what they know now, they would have tried harder on the first marriage. Sometimes, people think they will be happier with someone else. I'm sure that's true in a lot of cases. But, you are going to be pretty much the same person in the next relationship. So, if you're not happy with yourself, a new person can't make you happy.
