This is where IC and the law can clash. I would not move out of the house, or even out of the MBR, unless I was advised to do so by a L. IT can be spun after the fact by her L in a very disadvantageous way for you re custody and support if you can be shown to have "abandoned" her and/or the kids.
She's the one who wants to blow things up -- let her do the moving.
