Holy cow! That's some crazy stuff going on. At least you got some good cuddles. Woman's point of view on this...that's tough. I think you can safely say she does care about you, but she's taking care of herself - she wants to be held/have attention and she's not hitting bars, she's coming to you and she's not sure she wants to stay (but at least she is being honest with you about it).
Keep on with the baby steps, don't get hopes up or sucked in (you know backslides happen), and play her like a fish on the line. Let her hook herself good and deep.
I don't remember - was cuddling/non-sexual connection to you an issue for her? It sounds like she was tired, you gave her a safe, positive interaction and comfort, PLUS made her feel listened to and appreciated when she was looking for that. And at that moment she was very attracted to you.
Faith is, at one and the same time, absolutely necessary and altogether impossible. --Stanislaw Lem
