More accurate to say they've exerted more control over who chooses them than you might think. But yes, it's rooted in a girl being property passed from father to husband, and that is a terrible legacy.

I like the idea of marriage as being a brake on breakups - knowing that a split will be a hassle gives both parties a chance to cool down and reconsider. But if it doesn't become more of a partnership it isn't going to last.
