EA, what a horrible way to treat family. I completely agree when an organization has that much of a hold on you to shun your family then something is REALLY wrong.
although she may no longer be a virgin to give her titles like whore and prostitute are completely wrong.
My heart sank and tears came to my eyes when I read how your in-laws treated their granddaughter and how HER OWN parents allowed and accepted this course of action.
I truly hope both of your neices can get the professional help they need. They are young and have a full life ahead of them. You are a God send to keep showing love and supporting them. They have no one but you to lean on.
