Just think that he is some kind of sh!t that doesn't even need ur attention.
Face it, we will all face some break-ups along the way to find "The One". But then of course, many tears will come along the way. (

)
However, be happy. Stay strong. Pretend that ur life is perfect. Try to talk to another boy to make him jealous. BUT REMEMBER, do NOT make use of that guy.
Or, if you have a good friend who is a boy, ask him to pretend that you two are "lovey-dovey" and get him dripping with jealousy!!!!!
Trust me. I broke up with my bf one week ago, and I feel sad. But now, I set my eyes on someone else already

and I just think that this is just another set-back in life I must accept.
Don't think of that jerk. Don't even THINK of it.
I am sure that you are a big girl already. Just don't think of him. Don't even be together with him again after he comes back crawling to you. You can just say "We are already SO over and we are SO not coming back. I already have my own perfect life, with a new perfect boyfriend, perfect LOVE.." and just anything to spite him.
Don't feel guilty. He is such a big dumb JERK.
