After reading your post, two things caught my eye:
1. is it possible to effect a change in such a short time
2. its her actions that have me worried such as the book for the kids
My W dropped the bomb on 01/12/2011 and told me that she was done, she wasn't changing her mind and that it was time for me to pack my stuff and go. (Which I did but that was my choice). She filed the paperwork with her attorney exactly one week later.
Two of our kids are in a dance class on Tuesday nights and I see W there every week. On that first Tuesday after the bomb (Only 6 days after I moved out) I was putting my kids in the W car and I saw 8 children's books about divorce that she had checked out from the library. All of these books were made to be read to kids to help them cope with D. Needless to say that when I saw these I was a wee-bit upset. (Especially when I read the title of one of the books "The day daddy left!!). I bite my tongue and never said a word to the W about them and I continued on with my DB.
I tell you this because my W never read those books to my kids. Not one. She never even took them into the house. To this day I don't know why she didn't do it or if she knew that I saw the books. I truly believe that in some cases the WAS will go at the D 100mph after the Bomb and I know that if I pushed W or blew up on her about the books my kids would have heard all 8 of them.
As for the amount of time sitch? I am nowhere near out of the so called woods. I aint even back home yet, but if you read my sitch you will see that on March 9, 2011 my W sat in a counselor meeting with me, looked me dead in the eye and told me that she has absolutely no feelings for me and had not been happy at all in our 9 year marriage.
Last night she kissed me goodnight. This was the first time in years I can remember that my W initiated a kiss with me. She has been checked out mentally for so long that if we did have any affection I always had to start it.
Things can change. Follow the book, try you hardest to detach, watch your back legally and don't give up.
