HuffingtonPost has this article talking about the 6 phases after getting dumped.  Now the article is directed towards women, but I think guys can relate too. Check them out below:

1) The wallowing phase-Immediately after a break-up

2) The bleak projections phase-When you stop being sad & become bitter

3) Trying to convince myself I'm better off phase-Self-explanatory

4) The I want them back phase-Also self-explanatory

5) The overly active phase-Trying to do everything to keep yourself busy

6) The snapped out of it phase-All of a sudden, you're normal again
