You'll make it through. I agree with CT1118 - don't be around. Take the kids and try to have a fun day.
The one caution that I will make is to not make the mistake I did. Well - I've made lots of mistakes - try to avoid this particular one. My W asked what she could take - I shrugged and said that the only thing I cared about being in the house was her and that none of the rest mattered. I did say that I wanted the MBR furniture left and my rocking chair.
Well - some of the MBR furniture left as did a "lot" of other stuff (but not my rocking chair). I joked to friends that I could dance naked in the living room without hurting myself. Perhaps you will need to do what some companies do when moving. You each get a roll of coloured stickers and put them on what you want. If you disagree then you'll have to work it out. One other thing that I wish I'd done was to do a "before move" inventory with the camera on my phone. I do have one from a few years ago that I did for insurance purposes though.
Those marital assets that your W removes will need to be taken into account if you get to the point where there is a formal S agreement and division of assets.
This is going to be a very very tough week or two. Stay strong and stay great.
