"I decided a long time ago to cut ties with my family due to their bad behavior."
I have done the same with an abusive family member. You have to let them know that you will not tolerate their behavior and as hard as it is, you need to RUN NOT WALK away from them. I agree also, that many of them love the attention they receive from other congregation members. "Oh poor sister/brother so and so, their child left Jehovah." Some really get off on all the attention. Very sick and disturbing.
