What with all the break up talk lately, thought id ask how many other dudes (or ladies) out there have a "one that got away"?

Dunno how common it is really, so not sure what kind of response ill get.

Anyways I dated this one chick who was pretty much perfect... beautiful, smart, high aspirations, great family
I was young (still am i guess lol) and was dumb enough to do lil shit that made us fight all the time... never invited her out to party with me, always sort of distracted by something else, she said i never acted like I "appreciated her"
Lost her over stupid shit like that and still regret it... never found a girl yet that measures up.

Anyone else have this experience?
