After close to 4 years together, which included talk of marriage, my girlfriend and I called it quits. Now it's a Saturday night (on a long weekend no less) and I'm all by my lonesome self--totally demoralized and spending time drinking beer and posting to forums.

Ever since I was 17 (I'm in my late 20s now) I usually had a longer-term relationship so I didn't have to deal with breakups all that much, and now after the longest relationship of my life, with what probably was the best thing that's ever happed to me gone, I have a really hard time dealing with it. Anybody have any advice to help me deal with a breakup with the love of my life?
