A few things: 1) Even walk-away wives can "act as if" in social settings, especially when family is present, so her attitude around them may not reflect what is in her head. I would encourage you to not draw closer in those situations (the WAW seems to later hate the idea of "the happy family" because it's an act).
2) I can not perceive how she would have custody of the boys. She doesn't do anything with them. If it reaches the point where these things are discussed, you should state that you think you are best suited to be custodial parent. They aren't even liking her right now.
3) I would address what your son heard with him, but not sure about with your wife. She may get half of the assets, but as I said, it's doubtful she'll get much in the way of alimony since you'll have custody of the kids.
4) In this uncertain time, I don't think you should be too open to the possibility of making a financial investment in any business your wife will open. Basically, don't make any big decisions (as a couple), until things level out.
