That's a tough one, but I would lean towards divorcing her. You see, if she really cared and felt bad about it, she simply just wouldn't do it again and would leave it at that. In my view, telling you doesn't show character, it shows her selfishness because she didn't tell you for your benefit, but for hers because she supposedly felt guilty.
if you have significant assets, I would be careful here but I would kick her to the curb. I wouldn't let her know this though. I would make all of your preparations then when you're ready, have her served with divorce papers because the less time she has to prepare, the more likely you'll be able to avoid a really messy battle.
