I too was impressed by your approach Confession, there's a lot to admire about "heaping burning coals"! I wonder what you would do in my situation...
2 years after I'd stopped attending meetings my mother told the CO that I was in a same-sex relationship and judicial moves were made. I ignored them and it came to nought so I'm not disfellowshipped. My eldest brother immediately cut contact but my mother and other brother with whom I was in business remained in almost daily contact. My family had been close, they were good company and we socialised, holidayed etc etc but the closeness dwindled as I no longer shared their beliefs or social lives. They refused to spend any time with my partner, now of 7+ years. The business relationship ended and my brother still wanted to meet for lunch occasionally but it was chat-lite and all about his life and I stopped meeting him 2 years agobecause I found seeing him rather depressing. My mum I still see about once a month, she's in her 70s, and alone. We had been very close but her instigation of having me disfellowshipped seriously fractured that. We have worked through it and while she's interested in knowing about my life, wont be part of it. She's lovely but devout, and would cut contact if I were disfellowshipped.
So, I've cut my elderly mum some slack, but not my brother... does it seem harsh?
