This is a very sensitive subject for many former JWs, myself included. My husband and I left the JW back when our boys were 4 and 6. My only rule to their grandparents (his parents), was that if they come around the boys, they were not allowed to shun their father in front of them. I was not going to put my children through that kind of mental abuse. After my husband and I disassociated ourselves his parents came by only once, and they wanted to take the boys off to McDonald's and then the park. I told them, no, but they were welcome to stay and visit with the boys, and they did. A few days later I had learned their true motives. They weren't planning on going to McDonald's and the park, but instead, they were planning on kidnapping my children and taking them off to an assembly in a totally different state. Found this out through a close relative (not a JW), who had called me out of concern, but only after it was all over.
Anyways that was the last I heard from them, well except for a couple of other time due to non-JW family reunions. We learned that my husband's younger sister had gotten married to a JW and that JW has two sons. My mother in law was going around like the proudest grandma on the face of the earth, over these two "grandsons" who are not even blood related to her but at the same time totally ignoring her actual grandsons.
Then a couple a years ago, we again happen to be at the same location, a family member was celebrating their 50th wedding anniversary. Anyways my mother in law, still a JW, came up to my now grown sons and was trying to act like she was a very loving grandmother, but to my sons, she is a total stranger. It was quite uncomfortable for them.
Here in a few days and I am going to be a grandma for the first time. I can't even imagine why anyone can do this to their own children, grandchildren, and greatgrandchildren. Yes, she is still alive, and she won't even get to know the joy of meeting her great-grandson. Her two "grandsons" aren't married and don't have any children. They are busy working in Jehovah's organization, and not having their own families because you know how we are in the time of the end.
