yup, on top of that, go out and get a dozen cardboard boxes for her, ask her to start getting her things together and look for another place to live, tell her you're ok with this marriage being over if she doesn't care about it and if she doesn't care about the marriage or the kids, why does she need to live their with you & kids? She's living the single life, she might as well pursue a single life somewhere else, follow it up with this: "I can help you pack your stuff and help you move out, I don't mind" - if you do this, make it convincing, smile even, you have to believe it if you want her to believe it.
If she wants a single life with no responsibilities, you want a single life too, which means without her.
