I would throw in my 0.02 and agree with everyone who advised not to move out or give any verbal indication that you're going to. I think there are legal issues there as well as things that affect the family and kids.
That doesn't mean she won't move out. Mine ultimately did. But your focus right now should be on you and the kids. It's never wrong to do what's right, and if there are changes you need to make for yourself and the kids then stay home and do that. Whatever happens with the wife, your kids and you will benefit. She may D you, and I really hope she doesn't, but the kids and you will be together for the rest of your lives one way or another, so you want them to have that confidence and stability from you. It's important, no matter what your W or society might sometimes say.
And remember...when you're home and being a good dad to the kids, they will know that and see that and learn that, and nobody will ever be able to tell them different.
