I am in your shoes and understand what you are feeling- I did not DA but just walked away over a year ago, my JW mom carried on our relationship as usual, but since recent pressure from other JW relatives and elders, she told me today that she cannot do things with me any longer- her reasoning to me is "she cannot turn her back on Jehovah". I told her that I respect her decision but I will not turn my back on her and I love her.
You need to keep the door open and show them what they cannot display...UNconditional love- they are restricted by rules and told that the love they display has to be only on their terms- my advice is to be the better person, don't close the door...
I feel your pain too
