Need advice- I got the inside scoop on my best friends divorce

So my wife came home tonight in tears after having a night out with her friends and my best friend’s wife who broke the news that she no longer loves him is done with their marriage and is planning for divorce in early January. Supposedly my best friends wife described a side of my friend that I’ve never seen or thought existed, which is a scary thought because I don’t say best friend lightly, I’ve know this guy for 25 years like blood brothers and, if true, it kills me to hear what he’s become. I’ve known his wife maybe 8 years and they’ve been married 5-6. They have three girls all under 6 that are best friends with my kids and it just breaks me.

Part of me thinks I need to prep my boy about what’s coming for him and support him in the fight for his marriage, but another part of me doesn’t want to be a gossic girl who intrudes into his personal relationship with judgment and possibly unwelcome advice. I don’t want to miss an opportunity where I could be a catalyst to help them reconcile. Part of me wonders if I should try and talk with his wife about things, maybe talk her off the ledge get her side of the story and see if I can help her mend my friends heart, but I’d hate to stand idly by when I could potentially have an impact on my friends heart and their marriage in a few weeks time. Part of me thinks if I say something maybe it’ll kick his ass into high gear and he’ll fight harder which could potentially save their marriage or at least get it off the cliff and a better track.

I also don’t want to compromise my wife’s relationship with my friends wife by spilling her news prematurely, even though it’s probably assumed my wife would go and share this info with me.
