H, what are your goals with your W? Do you really want the R to just end or not?
I think one major advantage you have in your sitch is that your W cares about family and having your family together. I think if she was deprived of that some that might make her reconsider, but otherwise of course she won't. I think you should really try to do a lot of fun stuff with just you and the kids. Give her a taste of what D will be like. I mean if you still have hope. Karen
