Make sure you wallow!!! Get a gallon of Ben and Jerry's, pop in chick flicks (be sure to stop them after the couple breaks up and before they get back together) and cry. Gilmore Girls The Break-up Part 2 (on the season 1 DVD) is a great one to cry to! Spend some time thinking that the opposite sex is the worst thing to ever come to planet earth. After this you'll be ready to attempt moving on. Best of luck!
