I'm on phone with my attorney now. He's telling me there isn't much I can do while shes in the same house.
In most jurisdictions you can't remove a spouse from the home unless their is some kind of threat/abuse.
However, that doesn't mean that you can't tell her that if she intends to carry on with this man she should have the decency to vacate. You also might want to consider (carefully) the option of exposing, etc., and certainly curtailing your interaction with her.
