It sounds like you are in a solid spot if you can listen to her and not react. You cant worry about what she thinks about you now or later, it is irrelevant. The only thing that matters is how you feel about yourself.
In terms of boundaries, just don't answer her calls or respond to her texts if you dont want to (I guess you could block her). But you cant control what she does, just ignore it and dont let it affect you.
Congrats on getting this far in such good shape.
