Question for the girls?

Let's say you liked 2 guys -- One was a bad boy who was your ex b/f who you still had feelings for and the other was a nice guy who you kind of liked but wasn't in the best shape and you didn't decide to be with the nice guy. Now let's say after months of not really talking to the nice guy, you bump into him and he has a body like Channing Tatum or Christian Ronaldo and looked really handsome and cute. What would you say to yourself about letting the nice guy get away.
