I am fighting too, about how to not think about my ex.
I am not perfect, but I would like to think (and my friends all agree) that I was a great bf to my ex, we had an amazing 2 years before meaningless little fights and her need to kick-start her career made her decide to call it quits.
I am not trying to get my hopes up (although I think most of us has this slight hope in the back of our heads), but I do hope she remembers everything I have done for her.
