No, do not ask her to read the book. What is clear in your newer posts, and I don't know if it was in your original issues, is that you're really focused on her and what she has to do and the help she didn't get that would have changed everything. You only have power over you. You have to learn to handle your reality, to work on anything you need to work on, and to not try at all to fix her or get her to do anything. You'd be better off letting her think you're ready to let her go, but in my opinion it's bad to do that until you really mentally are OK with it either way. Otherwise it's a tactic to manipulate the outcome. You've got to live through this and be OK.
Positive time together, that she initiates, and that you meet on the level she seems to be at, and that you end first by having something else to do next, sounds like a good thing for you. Don't initiate it and don't push for more closeness than she's bringing, and don't expect anything from it.
