please DON'T go and die. from what you told me, i don't think that there is anything bad about you that your girlfriend hates. it seems that she has fallen for someone else instead. it is normal to feel sad about this. since your girlfriend has said that she likes another boy, i think you should move on and don't let this affect you. it is obvious that she doesn't like you (anymore) so there is no point in moping about her. i'm sure somewhere out there, there is someone waiting for you. all you have to do is go and find her.
