You made your boundaries clear that you did not feel it was appropriate to discuss in front of the children. I think when she pushed your boundaries, basically steamrollered over your boundaries I think & was verbally abusive also either would have been enough for you to say this needs to be a private conversation. I will not hold this in front of the kids. or I will not listen to this kind of verbal abuse in front of the kids. If she continues, which I'm sure she would, then I think you should leave the situation. Not allowing her to act like this and say stuff like that in front of the kids. She is hurting the kids and you shouldn't let her do that I don't think. Karen
