IF they changed their policy and IF your family wanted to be your friend again how would you react?
I would be cautiously optimistic. In reality, my life is very, very busy without them. I have more than enough family and friends I am in contact with regularly that, luckily, not having the JW family in my life (with the exception of my parents) hasn't affected me much, if at all.
The JWs is my family are on my Mom's side. They have next to nothing to do with me except when necessary family business forces them to. They are overall nice people but are mislead.
My parents became mean-spirited, self-righteous, holier-than-thou a-holes with us kids in their zealous days (this was during the 1990s). They did not shun us outright but they did withdraw somewhat during that period. Luckily, none of us kids ever got baptized.
The JW belief that they are "God's Chosen'', which elevates them above everyone else, would probably surface repeatedly with my other JW family members as it used to with my parents. I would not be able to tolerate that.
