Julie, I have nothing to add that hasn't been said. I agree with Zues, send him a quick text, no apologies or explanation, just an FYI. I agree with everyone else, you need to do what's right legally for your children. Do it now before he spends all of his money or loses his job or disappears or who knows what else. If it makes you feel any better, OW will be less attracted to a man who has less $ to spend.
