This is what Parental Alienation looks like!
I came home from shopping one day during the divorce (when I was still living with my ex under the same roof with the children because he refused to give me a financial settlement) and found this photo pinned to a dart board.
The holes in the photo are where I was used as a dart board by my ex and my children then ages 11 and 13! This was minor compared to some of the other things they were encouraged to do.
So when someone asks you what does Parental Alienation look like I am sure you have many examples of your own.
