I know how hard it is, but you need to let that anger and resentment go. I learned that the very hard way.
I found the easiest way is to view my X clearly as the person she is now, and not the person she was. And the person she is now, I want no part of, and from there things got better.
Prior, that anger would just pent up and then explode when X would do something, as most cheating X's do to get a rise out of you. It seemed like a rechargeable battery for my XW to refuse to face the facts of how many lives are now royally screwed up.
Adding up financials? Why bother, other than to just torture yourself some more, which we inevitably do to ourselves.
So hang in there, lookk at her for who she is now and ask yourself if she's really someone to be concerned over and is worth the wasted energy in all this anger.
