well sweetie, usually you'll forget about it when you find someone new. it helps if you have supportive friends and family. there's more to life than just a guy.
A short term solution is "Distraction" babe... Blunt as it may sound but nothing better than finding someone else to focus your attention on. you may not find a soul mate this way but it does make you feel better for a while. Then again, you may lost control and fall in love for the wrong reason again...
Alternatively, do what HQ says... Find friends and do something new. Wanna come dance with me? Yes... you can bellydance even if you're not fat... ;)
