try hard to keep the financials apart from the kid issues and let the L's do the money stuff. I KNOW it costs more at the start, but it saves in the long run, financially AND MARITALLY..
It means she can see you emotionally as separate from what is happening legally, and that's huge.
Plus, your approach to money (vis a vis Her) has to be about saving for the kids, and investing for their college, the home, and never about your new car or trip. Get it? You're just being careful with the FAMILY money and NOT implying a thing about her or spending. Plus I am SURE she does not look at the spending the way you do. I would bet she's totally justified it and feels entitled to a little "me" money. In reality, there's probably some validity to that.
But Remember, when you speak to her, you can say you KNOW SHE WANTS WHAT'S BEST FOR THE KIDS OF COURSE...and mean it. (OR sound like it)
