Whatever past the two of you have shared, her life belongs to her and your life belongs to you.
Your post sounds as though you would be happy/happier with a dramatic Final Scene. She seems to be avoiding confrontation--and she has every right to do so.
By wanting the Final Scene (which you admit is for your benefit rather than hers) you are the one who is hanging onto the past.
Why does she "owe" you a few hours? So that your memories will stop getting to you? Doesn't she have a right to leave her past in a bit of a muddle? Perhaps she has dealt with this time and moved on.
Perhaps you should deal with the past--all by yourself--and move on. She is not responsible for either your happiness or your sanity--you are.
