IF you even want her back in her current state (and I agree with Cadet, she still sounds pretty "woe-is-me," and I wonder how much work she's REALLY done on herself these past several months . . .
I would respond with something like "You know what my conditions are for a reconciliation; they haven't changed. If you're ready to commit to that, please let me know. I don't expect you to be able to guarantee your FEELINGS for me for quite some time (and that will be difficult for me to guarantee as well), but the ACTIONS I would need to see have not and will not changed."
