First, no way shape or from do you show her the DB book. The analogy is that is like showing the other teams the playbook.
Second, you are trying to use logic and reason to understand an emotional human being. You may want to read "Men are from Mars and women are from Venus" to help you understand the differences in which men and women think.
Third, in no manner should you be bringing up relationship talks. That is a big no no here that will make her feel pressured and will make her want to flee even faster.
Last, for all the things she has done to you and you are desperately trying to get her back is going to communicate to her that you have a low value of yourself. Not saying you have to file for D and close the book on her forever, but she needs to earn another chance with you. Know what I mean? She has to choose you and do the work. That's the only way it will work long-term.
