Just because you get married doesn't mean you'll be with that person forever. If I believed in marriage, I'd be married and divorced like five times by now. But I feel like I'm married because I've been with the same person for ten years. I think it's crazy to willingly add unneccessary legal complications to your life. I really have never understood why so many people do it.

(Conversation with my Dad--
Me: I think you need to go out with somebody like for a year before you really know them.
Him: No, you don't really know someone until you marry them.
Him a few years later: No, when you divorce somebody, that is when you really get to know them.)
