Dear Ddawg:
My first suggestion is that you send her a one time message telling her, (edit the following) that “it keeps setting me back seeing her name pop up on my phone. So I made the decision to not respond.. I need to heal and honestly, so does she”, letting her know that you will no longer contact her and that you need her to no longer contact you.
I am suggesting this as an alternative to ghosting her.
