As a child, I was alienated from my father by my mother. I was scared of him, didn't like him or trust him, and didn't want to spend time with him. Now, as an adult, I know that it was my mom's messed up stuff that caused it, not anything my father actually did. So I can see how AW's sons might have been turned against him by the two adults they lived with. It is a common occurrence in split families.
That said, eventually the whole story will come out. We'll find out why Kristy left her children's father and her husband. We'll find out why the parents were separated for 2 years before divorcing this June. We'll find out what the boys experienced before and after the break up. Were they used as pawns by one or both parents? Were they isolated from everyone, including Kristy's mom? We'll hear from their teachers. BTW, I was able to watch a video of Mariah reading with her mom, in the presence of a teacher. Looked like a preschool special ed type of home visitation. Can't see the video any more, but I remembered someone asked about Mariah in preschool.
