Statistics say that your W probably starting thinking about the divorce before you moved and before your D was born and that the move was her last ditch effort to be happy. It's very common and we see it here all the time that WW drop the bomb after being in their dream house for 6 months. They are acting on emotions and not logic and reason.

I know that you don't believe it now but I promise you that two years from now you will be ten times happier then you feel today. I can guarantee it.
