Treading water

Perhaps you could say something like, "I'm sorry to hear that. I hope they're each doing okay." You could acknowledge that it's a difficult process, without trying to say anything about whether it's a good or bad thing for the couple.

Another tact might be to bring up how common divorce is. "Yeah, a lot of people we know are going through it. Marriage sure isn't easy." Sort of, we're all going through this mess together type of approach.

I guess what you say depends on whether you think she's making a point in bringing it up. If she's trying to point out that everyone gets divorced, it might be better just to not say much in response.
