>Do ever think about the one that got away
Nope. Because it wasn't that she got away, but that she said no. There's a difference. I got over her and am happier now.
I gotta also say that Karma is a bitch. I've watched her fuck herself over really hard with the lovers she's taken. So if you reject the one you're supposed to be with, Karma will fuck you over.
>or do you have a failed romance?
Of course. That's why we have ex-girlfriends.
