I have made it crystal clear to my JW mom that we are a packaged deal. She seems to think she can have her cake and eat to. She wants to be a grandparent to my daughter but still play the semi shunnning to me and my wife. That is very toxic and my daughter will not be exposed to it. She has another normal set of grandparents that she can spend all the time she wants with.
All of our JW parents have different levels of cultish behavior so we have to handle them according to our own intuition and judgement. My mother is a manipulator and expert at mindgames so she is out of the picture for now. I have seen other JW parents be completely cool about boundries with grandchildren and actually have a close to normal relationship.
