Don't over think it. My W came to me two weeks ago and sobbed and cried and said she loved me. A week later she was dead set on divorce. A few days ago, she changed and wanted to think about things, to be decided this Friday.
I stopped getting hopes up and just took each positive and negative as about 5% of reality, and I was able to be calm, funny, relaxed, etc. So read the book, thank her for it, and let her ask you about it. Same with email.
