Here's why. You made out with another guy before you broke up. Me made out with a girl after you broke up. See the difference. I wouldn't take you back. Anyway, there is clearly something wrong with your relationship and you both clearly want to play the field.
"Oh Lord it's hard to be humble, when you're perfect in every way. I can't wait to look in the mirror, cause I get better loking each day. To know me is to love me, I must be a hell of a man. Oh Lord it's hard to be humble, but I'm doing the best that I can." Mac Davis
