2thepoint has great feedback. I am a few weeks into my separation with my walk away wife (WAW). The Divorce Remedy and Divorce Busting books helped tremendously.
You had mentioned that you told her to contemplate what she is leaving. According to what I understood from the books, I would have not done that (of course I did it the first few days before reading the books, but immediately got on track with not). You see, the way I understand it is that this isn't a sudden decision for her. She has been thinking of this for a while. So yes, she has considered what she is leaving.
Though, the GREAT news for you is that she didn't know what you are capable of. Stop perusing, get a life (GAL), do it for yourself or it won't be authentic. Treat her like the "casual neighbor". I think this means being friendly, respectful, fun, happy, smiley, not depending on them, and most important is if she decides to communicate to you that you LISTEN and let her know you UNDERSTAND. Though don't be rude, don't make them feel bad, and don't try to fix.
Something someone told me that I keep reminding myself. She will be "testing" (you and/or herself) to prove to herself the marriage can't work. Don't fall for these. Stay strong.
