How do I learn to move on?

I couple of months ago I fell in love, but I took him for granted and messed up. now im a total mess cause you really dont know what you've got till its gone. well I havent seen or talked to him for about 3 weeks and im going crazy! someone please help me =[

aw break ups suckkk ! if the relationship is ment to be it will happen once again.. try calling him and telling him that yyou took him fro granted? if not, just have fun with your friends and check out other guys while waiting to fall out of love. its the worst feeling D: ..good luck :]
