Video games don't help. If you want to move on quickly I'll give you the advice that an old school biker friend gave me "go find two girls to get over the last one." That is the best break up advice I've ever received in my life. It's not the high road, but it works.
I'd suggest finding these two girls:
I'm the one in the back.. I'm actually ashes girlfriend
I must say, I'm lookin' pretty hot in that pic!
