Recently my oldest son had open house at his school. My ex and his girlfriend showed up. The girlfriend spoke to my son's teacher asking her several questions and even signed up to volunteer for his class. She and I do not get along. She has caused several problems and has been the driving force in many of the disagreements between my ex and I.
I felt very much like she was over stepping boundaries by her doing this. She has no children at this school, in fact her six year old daughter goes to a completely different elementary school.
Any opinions or similar situations?
