Anytime you relate anger to her is burning a bit of the bridge. If you do divorce, I now think you have to come to the spouse telling her that for your own health, you're having to move on. I see so many in anger say they'll never forgive, say very hurtful things to push spew back on the cheating spouse, and dump so much landfill onto the spouse that they can never see the lifeline you could provide.
What if she realizes her problems are really her problems, owns them, and comes back in 5 years a changed woman?
I know you can't stand around forever. No one is asking you to. Just don't let the hate overtake you. It didn't work too well for Darth Vader, it won't work for you, either.
