Yeah, there was a girl who I took to the school ball in my senior year who I was totally obsessed with. At the after party I found her in the arms of one of my best friends, who I found out liked her too. It was a betrayal that I wouldn't have gotten over quickly if it hadn't been for her pretty much ditching both of us
for some guy who we could both hate together. :D

I got over her far faster than my friend did, thankfully.
