My ex-boyfriend/best friend hates me and wants nothing to do with me, is that normal?

You need to play as though you dont care and that you moved on . Guys like it when women act as though they dont care, when you are hard to get. It will be hard to do, but you need to do it. If it meant to be and he loves you, he will come back after he see that you will move on if need be. Good luck !!
