Hi John T,
It sounds like she is just trying to be "friends". Because if you are friends, then what she has done is not so bad, you see. It is up to you if you what kind of relationship you want to have with her. You can be friends, just be friendly, only answer when she contacts you first, only answer if it is important, go No Contact. Whatever it is that works for you.
Take what you get as exactly what you see: she wishes you well. I doubt there is any other underlying thought behind it. (except maybe "I wish you well so I don't have to feel bad about what I have done.")
