Careful with broad brushstrokes! I totally understand the author - I had to break with my single-parent mom when I was in my 20s because she was so manipulative and abusive with my wife. I was able to put up with her controlling and immature behavior it when it was just me, but not when it affected the love of my life. She would have never acknowledged or changed in any way. The funny thing was my wife was always trying to get me to reconcile with her because she felt it was important - I just couldn't do it anymore.
