I think the only way I would get married is if the spouse has about the same assets and income. That way if their is a divorce, which is highly likely in todays flaky culture, no one gets screwed.
Marriage can be a real set back. If you let someone who has nothing, move into your house for 1 1/2 years, your married. If they would like they could then separate and force you to sell your home, to split the equity. This has happened to a couple people I know of. Doesn't sound to romantic to me.
