I was hoping when you took a break that things were getting better for you.
I wish I could say I was surprised. I've read enough threads here to realize that when a WAS says they will keep the kids away from the AP, they rarely keep their word.
As for D22, I think the message should just be that what is happening with your XW makes you sad too, but her Mom will have to walk her own path. Regardless, you will be there for her (D22).
Did your XW ask the kids to keep this a secret from you, given that she knew how you felt about it?
This is all still pretty fresh for you - give it a day or two to settle. You're strong enough to protect your kids.
