How would you feel if you were reading this email?

You've already sent it so I can't offer much advice. You do repeat yourself quite often. You should have never said you were out of his league. Many GREAT relationships begin with friendship, you didn't allow it to bloom in it's own time. You lack confidence. If you act like a rug you will be walked over. First of all, Love yourself first then you'll attract the person your meant to be with.
