Everyone gets dumped as far as I know. I have heard of some whose family still speak, I havent spoken to my JW family since the day Ieft,
My dad is an elder, my brother is df'd, my dad goes around to help my brother on his house, when we are all in the same place we sit and eat dinner together, even when I'm not there my brother will go and have dinner with my parents and grandma (grandma who is roman catholic). My mother said that if anyone tried telling her she had to stop seeing her son/s, she would tell them that she would never stop, and if that got her df'd, so be it.
