You are reading too much into her "confused and torn" comment. She is feeling that way because she had told herself that she was done with you. Now she wants to come back. She is a bit skeptical, but she is warming up to the idea of R. You say she is a somewhat stubborn person, so she will naturally be a bit "confused and torn" because she has changed her mind.
You know better than we, but I really do not think much, if any type of A went on. You describe the OM as someone she plays music with, so I get the feeling that there was waaaaaaay more going on in his mind than in hers. She was flattered by him and maybe a bit smitten, but I would seriously doubt if she considered him much more than he really is. JMHO.
Man, you are there. I am thrilled for you. Just tread lightly, shed some doubt to her. It will validate her feelings and take her guard down and show her that you are serious about fixing things and won't just fall back into the same patterns. Your doubt will also let her know that she has some work to do without you coming out and telling her she has some things she needs to work on.
Great work!
