Um, this is strange. Since we broke up on sunday we seem to be getting along great. I think we just make better friends. Now that I think about it, the only things we fought about were relationship shit. Lets just see how she reacts when I start hooking up with other girls though.

You two seem better off as ex's... maybe even friends, kind of like Seinfeld.
