NOTE : DO NOT TELL her you are planning this. DO this as the most inconvenient TIME. Do this in the middle of the night. Take your camera and have it ready too.

I would also reccomend taking some vacation time from work, say five days worth, to use up right after your move.

This should be PLANNED WELL by you, but don't tell her you are planning it. Its a big move and all variables should be considered. But it is VERY IMPORTANT that she does NOT KNOW you are planning this move.
