You haven't done anything. To her you have though...you are in her way from getting what she wants. Just be prepared for the nasties but don't take it personally. If she wants out, she can leave. Continue to be a good boy and don't let her provoke you. She is being coached on how to get you out of there. Wear a halo. Walk away if she confronts you.
