Nice simple and clean flash, but you're not doing yourself any favours. Just imagine she came back to you today. Then remember all the bullshit that you went through when you were still with her. Your self-destructive emotional dependence only serves to reinforce your insecurities and hinders your spiritual development. In the words of The Barenaked Ladies:
"Jane... desired by the people at the school and work
Jane... is tired, 'cause every man becomes a lovesick jerk"
And in the words of Doc:
"Where we're going... we don't need roads."
