Romance Regrets: What Relationship Mistake Would You Take Back?

We all have regrets. And it turns out, when we look back on them, it's those tricky matters of the heart that we dwell on the most.

When researchers from Northwestern University's Kellogg School of Management recently surveyed 370 American adults about what they regret most, romance-related missteps topped the list -- and even more for women than for men.

What's that about? Do we look back and see possibility in relationships where there actually was none, or are we pretty bad at identifying and choosing the relationships that will make us happy in the long run? You tell us.

Maybe you gave too many second chances to a man who ended up not deserving them. Or you wrote off a guy who now seems like he might have been perfect for you. Whatever you wish you'd done differently in love, we want to hear about it.
