Definitely no. She is the one that has to feel sorry about that enough to do that...otherwise it is not really her remorse but yours. You may be thinking of the addiction and how getting over it would require something like that, like a 12-step program of AA or something. But, in this case, she is past that point and in a good place with you and trying to leave the past in the past and move forward. This is not important. It may be the "right" thing to do, but it has nothing to do with you.
