Another note: some people say it's possible to remain friends after a break-up... my opinion is it isn't a good idea. There's always going to be one party who will harbour some kind of residual feelings for the other, whether it's a feeling of longing or jealousy, etc.
Good luck man, this sorta thing is never easy.
Currently learning this part the hard way. Le Sigh.
@Tireyo643: first of all, downer. second of all, I totally agree that single thing, or even collection of things, is going to make the pain go away. Right now, I just want a temporary distraction so I dont end up calling her tonight.
