...the best voices of reason that will be in her life...
She is making decisions using emotions, not logic and reason...
You can use logic and reason to change the way you interact with her to change the way she feels about you.
First thing that is needed is her missing you. You fight every urge to pursue and you distance yourself. You are always the first to end interactions. You are busy and have something more important(exciting) to do. Always be on purpose.
When you are interacting, you behave more attractive than the old you she left. That is one huge onion to unpeel. Understand how to build sexual tension.
Do not let fear control you. Face and slay the dragon.
Do not be boring.
