I am so sorry that your H put your kids through such an immature and childish situation. You must feel so helpless knowing you cannot do anything. I think you are getting good advice. Stay out of it, but also get your kids the support, love and help they desperately need right now. Even if they don't show it, they must be struggling very much.
Please take care of them and yourself.
