3. Bigger bucks.
Though the income gap between men and women is long-standing, some women do make more than men: Women in their 20s who live in big cities, most of whom are single. They earn up to 20 percent more than single men, a Queens College study found. The same did not hold true for women over 30, or those who lived in rural areas. Why? Because those women were more likely to be married, researchers speculated. Let Rush Limbaugh call me a crazed feminazi, but I like earning at least as much as a guy for the same work. (And single women aren't just buying Manolos and Balenciaga bags, we're also investing in homes; in fact, single women bought about 20 percent of the homes on the market last year.)

4. We can still fit into our "skinny" jeans.
Ever been a teeny bit jealous of how great a bride looks? Don't be, because chances are she'll be gaining more weight than you in the next few years. A recent Cornell University study that single women gain 15 pounds between their late teens and early 20s, while married women gain 24.

5. We're better in bed….
even if we're the only ones in it. Australian researchers found that 55 percent of single women could achieve orgasm every time they masturbated, while only 25 percent of women with a current partner could. And a British study found that married women were significantly more likely to report sexual problems than single women.

If you've read this far, here's a bonus reason it's better to be single of Valentine's Day--just for you. (Think of it as the hidden track on your favorite album.)

6. There are record numbers of single men out there.
The best news a single woman can get on Valentine’s Day: Forty-five percent of men in America are unmarried. With so many single men out there, meeting the guy of your dreams is really just a numbers game. He's out there, you just haven't met him yet. So why not get dressed up and meet up with some other single friends this Valentine's Day, and check out a few more. One of these nights, you're bound to meet Mr. Right.
