The awkwardness after a breakup: What goes through your mind?

You know that awkwardness after a breakup when you're around your ex? Why are you being "awkward", what goes through your mind?

I personally tend to love them(whether I told them or not) and really want them in my life but am hurt we're not together and don't know how to act( we can't act like before) and I don't want them to know I'm hurt.
