Read the does and don'ts on this website. Looks like you have met some of the good ones already.
In respect of the DB book, keep it to yourself, don't even let her see you reading it. I am treating my sitch as a war and using all the ammunition and information to my best efforts.
I totally agree with everything that all the other posters have said about the seperation. Explain to her that you love her, you are willing to give her space, but you are not going to pay to file. You can always say you originally agreed because your emotions were all over the place (I agreed to everything originally).
One of the best things you are doing is looking after yourself and your children. Now the really hard thing to do is 'not chase', in fact no relationship talk at all.
At the moment she will be trying to push your buttons and you have to rise above it, walk away and be the person she fell in love with.
I know this goes against all the natural order of things (does for me), but boy does it work. I have gone from 'I want you out and a spereation for several months' to 'I'm trying to sort out my work for our holiday in October'. You will slide - we all have, but be strong, use this website to vent your feelings and act 'as if' everything is great.
