Wow Paul,
I sympathize with this and understand why others are saying to try to have a lighter touch. But honestly....what she has said to you repeatedly is just terrible.
In the end we are all responsible for our actions. I read your thoughts and what she said and wondered to myself what i would have said in your case. One I wish i would do, the other I would be tempted to do.
1) Mom why are you calling me? Is it to try to get me to see that my own mother shunningme, shunning her grandchildren, showing zero love an affection, abusing her children as youngsters, and telling her grandchildren that they will die and are doing things God hates when they were talking about extra curricular activities......is proof that i should come back to the religion of my youth? You are insane, and not welcome around my children. Jehovah has already removed your "parental love" from your heart, as I certainly can't remember the last time I or anyone in my family experienced it. Kick rocks mom.
2) click* (ring, ring).........click x 2*.
Paul my mother once (not directly), suggested....that I could be leading my children to death due to my actions. I already know this is what was taught....I gave a talk about it once. So I told her.......you get that one. One. You ever suggest to me that i am killing my children directly or indirectly, and that is it. You know in your heart that isn't true. I won't speak of this again and will forgive you.....this time.
