To say that you just shouldn't marry someone if you're not 100% sure or committed, is being terribly naive. How many people do you think are divorced right now that were 150% positive they had found their soulmate for life and they would be married forever? It can happen to anyone.
If you've got assets or children, you should always get a prenup. If someone doesn't want to sign, then don't marry him/her. And if you're *positive* you'll never divorce, then it really doesn't matter anyway because you'll never need or see the paper again after you both sign it. Do it, put it away, and forget about it.
Or just shack up. That's a whole lot easier.
