Yes it is scary. I understand the depression that is tough, been there too. But this is more about you than anything, making you a better person and really looking at what you did and what you can do to make the situation better. You may hear this over and over but you can only control you and remember she will do what ever she wants to when she wants to do it, and you can not do anything about it. But the thing that you can control is the way that you react, acting AS IF. Yes it is very hard to do, trust me there, you sometimes have to be the best actor in the world in order to pull it off.
Also what did you think that you were going to accomplish by give your W a copy of the book? I don't mean to sound harsh but really, its like giving the other team the play book and hoping to win the game. She will be looking for the changes and will be able to combat them, is that what you really want? But that is only if and that is a big if she has even read it.
Also the rollercoaster ride that you are on is not going to stop anytime soon, unfortuantly. It took me a while for the ride to start to slow down and finally stop, just for me to get back on and ride it again, and now its coming to an end again, I hope. Jump over to my post to read my sitch and you will see, its self inflicted this time and I have finally realized that I was wrong very wrong and H and I are working things out for now.
Now a tough question, has she talked at all about filing for D yet? I know that you are not going to be the one that does, at least that is what I am gathering from what I have read so far.
