Steve, i don't know if I am enabling my W by keeping in confidence between what parents are speaking about. When I think about it, I actually think this was a very unselfish act on my W's part. She was coming back from the "friend" side with my D and her friends and sharing parent to parent information about the teenagers and hoping we all can work together to make them better people and away from making huge mistakes.
Nothing for you to really do on this. But W needs to be an adult and tell D, "I told so-and-so's mom." Likely she won't but it is not like she is coming back from the friends side as much as she'd trying to be on the fence.
