She's trying to manipulate you when she says it helps her "detangle". This is seen a positive, she hopes you see it as an opportunity to reconcile so that you'll soften up and give her what she wants. She's trying to put the negatives of her moving out (such as D4 not being at "home" all the time or her needing another job for more money) and use that to get you out of the house 3 days a week. F that. Your W wants the divorce and separation and you don't, this is a consequence of her choice.
And if that bed in the MBR disgusts you, get rid of it and get a new one.
