Yes, Tommy that's all you can do at this point. You may just have to accept the fact she resolved this on her own, to herself, and moved on some time ago. She might not want to open a can of worms. You did what you can in making ammends. What comes from it now is up to her, and if she choses not to act on it I'd let it be at that. Anything more than that I personally would feel would be pushing it.

Just know you have come this far in your own personal growth that you can see the err of your ways, and you are making strides to make them right. Those are big steps.
