I hate you, but my wallet can't live without you.
The Washington Post has an interesting piece about couples who have postponed divorce simply because they can't afford it. The article also mentions people who have separated romantically, but still live together.
Because -- you guessed it -- they can't afford to live otherwise.
I'd argue the issue isn't confined to married couples entering splitsville. When you've been dating somebody for a decent amount of time, it's only natural to think of the economic ramifications of a split. It can be a little disheartening to realize you'll finally have to buy your own dinners...or your own lawn mower.
Then again, financial issues can be a ray of light in a breakup's aftermath, too.
Once, when a friend broke up with a guy around Christmas, I watched her smile amid tears and say, "Well, at least I won't have to buy him a present."
It's also nice to think of all the money you'll save without having to hit up your former fling's favorite overpriced restaurant monthly.
