OP says kids are involved in both sides. That's reason for concern as the situation could be very upsetting and confusing for kids; however there's not a lot OP can do except decide how she will act in front of her own kids and how she'll answer any questions they ask.
OP--are your kids and the woman's kids friends? Friends outside school? Maybe just classmates or in the same school but different grades--? The existing relationship if any between the two sets of kids does matter here, I think. If your kids and hers are goo friends now, this change could affect the kids on levels beyond just "dad and mom are divorcing."....In your shoes I honestly would see a therapist or counselor ASAP and ask for help both processing your divorce yourself and help deciding how to talk to your kids when you're emotional and angry. I'd need a script to help me stay calm when having to talk to him and a plan for how to react if I ran into her.
I'm sorry about this. Same thing happened to two families I knew. The dad ended up marrying the family friend pretty soon after the divorce was final. If that happens in your case, all the more reason to get outside help and ideas on how to present as the calmest person you can be for your kids.
