I thank everyone for their input. In the past, I've only allowed my daughter to see them with my supervision. I've been there to try and protect her from them.
Being a teen, she thinks she's old enough to protect herself now despite some major problems that have happened even with me to protect her. This letter basically told her they only put up with me until now because my daughter was so young and now they didn't want me around any longer. Can you imagine how they would react when they found out that my daughter is now interested in Wicca? I told my daughter that she would be "shunned" every bit as much as I was if they found out and her argument was that she could wear a "mask" for any time she spent with Grandma. See Grandma spends money on her that we don't have since I'm a single mom.
This whole thing almost sounds like something an ex would do to mess with a kids head.
I agree with you that it would not be a good idea to allow her to visit them alone. But how do you make that valid argument to a teen?
Hurt and Frustrated,
Tracy
