"You don't marry someone you can live with - you marry the person who you cannot live without. " - - Unknown
One day a few months ago a friend and I had a discussion about this line. We were talking about the meaning of the words per se, and whether it should be interpreted literally or figuratively.
Literally, this won't work. You really should marry someone you can live with. Otherwise, you'd end up in huge fights everyday. And eventually break up. But of course you will never know if you can live with them, well, until you live with them.
But then again, figuratively.. You marry someone you are crazily in love with, someone you choose to spend each and every day with, someone who you need because you love. But how do decide who's that one person you cannot live without?
