This is stupid. The only way to win in this situation is to make her wonder. It pisses my ex off to no end that I'm out with other girls at bars/parties/photographs on facebook. I'm not being a dick, and I don't flaunt it in places that I know she will be...but I know she finds out because she is sketchy and asks people. Some of them I'm with, some not. THAT is how you move on, not by jumping into another relationship and bragging about it...by simply demonstrating that you have moved on and that plenty of other women are interested in you and you may or not be casually interested in fornicating with them outside of wedlock. Which should be the truth.
