Dang. Sorry about the divorce, lookout. I have friends who are currently going through the same thing -- he decided he found someone who "got" him, and that was far more important than his wife and kids.
chimmi, it's not my place to judge you. But you might consider what a vow is, and the reasons that a serious one is important. Does that mean that you are condemned to a life of boredom (or whatever it is that you're feeling) with no escape? No, it means that sometimes living for someone else is a richer existence than always thinking about "what am *I* getting out of this?" It's all relative to one's outlook. If everyone decided to get a divorce as soon as they weren't having their "needs" fulfilled, the divorce rate would skyrocket.
