I actually stepped down, kick the book study out of my home and refused to even carry the mic. I did go witnessing, but only with my Bible. I eventually moved 50 miles away and despite the elders attempting to reach us, we just ignored them. We became inactive. We did run into Witnesses while visiting my in-Law and no one treated us like lepers.
Of course we left in the early 90s so who knows what "New Light" they may have come up with. To my knowledge we were never announced as disfellowshipped. My in-law would have definitely informed us. Not that it would have mattered to us. we stayed "in" because of her, but when she found out that we didn't believe in it anymore, she threw us out of the house.
