Oh Wow. I feel like i've had my heart broken...?

Best way is to just forget about them. It will take a while but my advice is this. Delete his number from your phone if you have a myspace/facebook, do the same. Best way to start to let go of him is to get rid of everything that reminds you of him. Focus on friends and family. They're going to be the ones who are always there for you. Don't bring yourself down over a relationship. Hold your head up high. There's always a good reason in the end why it didn't work out.
