PERHAPS she won't go back at all???? PB ~ when you tell her no contact with this predator to your marriage and family, you better mean it. That means she can find another place to do whatever TKD is. Or find another hobby. Or something, but going back there would mean contact and that crosses your boundary.
He told her to cool it b/c dating a married woman with children is frankly just a lot of baggage. Is he married, by the way? And going back there would be humiliating and most uncomfortable for her. Maybe he's asked her not to come back - that's a possibility. At any rate, IF she does have contact after NC is agreed upon, you know what to do. And don't let her think there is an inch of wiggle room. Otherwise, she'll be wiggling right out of it. We've seen it here before.
