I know you say she is stubborn, etc., but I don't think she doesn't have a conscience. She is definitely thinking through what she has done. I think you know that, for me, even though I felt bad right away, it took getting closer to my H before I realllly starting feeling what I had done. Don't underestimate her guilt and remorse. Actually, she could be ahead of me in that she is working on forgiving herself so she can move on with you. Think of it that way.
