If you're married to someone awful and the relationship can't be salvaged, then end it. But don't humiliate them like this. The only place where it might be appropriate to share such a thing is if they were in therapy and wanted to talk it out there, or possibly as part of divorce proceedings. Not online to anyone who wants to watch.
I see they're getting divorced, which is probably for the best. I hope she gets some counseling, because it certainly looks like she needs some serious help.
