I would be careful with leaving R type articles around and suggesting books for her to read. That is pressure with a big P. It also tells her that you are not respecting what she is going through emotionally and you are trying to fix her feelings. That is a death knell my friend. You heard the huff, and the book has not been read. That tells you NOT TO GO THAT ROUTE. In all probability she says to herself "sure, now he leaves articles and books around, he's just trying to get me back, where was all this before?.." I don't think thats the response you're looking for Sooner...
Respecting her space and not trying to persuade her to change her mind will go a heck of alot further than any book will. Show her you respect what she feels and leave her be, its on her timeframe. Read the book, apply the principles yourself, but don't even remotely hint that she should do the same.
