I'm sorry to hear both of you are experiencing difficult times.

You've referred TWICE to what you were expecting of her...but...

...your expectations are just that...YOURS. I don't think you have a right to try to place them upon her.

If you've truly clearly and sincerely said to her that you made a mistake, apologized and offered to do whatever it takes to try to fix this, then it sounds like you need to just give her space and time...and hope that she finds it in her heart to forgive you so the two of you can try to work things out. But if she ultimately can't get beyond this, then you both will need to move on with your separate lives.
