Besides tax breaks and societal norms, I haven't really figured out why non-religious people get married in the first place. My dad and his gf have been together for like 17 years or something, not married, not tied in place by a contract, just happy. If you don't want to be with someone, don't be with them, if you do, do it and enjoy it. Marriage complicates things it seems. On that note, I can't say I won't marry someone at some point in my life.... i want lower taxes too dammit.
