Revenge

AITA for rejecting a girl as revenge?

So, to start off, maybe, it was a bit petty of me tbh. Anyway, I asked this girl Clara out on a date about a year ago. I was a completely different person then, and she turned me down. It stung like h**l, but it did encourage me to better myself. Since then I've gotten in better shape, became more confident and generally I've had more luck with girls. I still never forgot what made me improve ...
