Break Up Rules 101: 5 Things NOT to Do After a Breakup. A few tips after a break-up to help avoid humiliation and help you keep your sanity.

1. Baby, I'm Begging
Desperation is never good. Wipe the tears and snot off your face and walk away with some dignity.

2. LOL :)
Texting him to say "I was just thinking of you" is no longer romantic or sweet, it's annoying.  

3. Breakup Sex
Really a bad idea.  Your "long history" does not make you immune to jump-off status.

4. Social Stalking
To avoid looking crazy, you should refrain from showing up where you aren't wanted.

5. Friendly Fire
YOU CANNOT BE FRIENDS WITH YOUR EX IF YOU'RE STILL IN LOVE WITH HIM! You're only setting yourself up for heartache when the reality hits that he doesn't see you the same way anymore. It's best to get over the person completely before considering his friendship.
