Hi Stumbeline, I have been lurking around here and there for a little while, but something about your post inspired me to come out of lurking. First of all I would like to say that although I am not DF'd, I sympathize with what you are going through. I was actually going to suggest just what LisaRose posted, to perhaps consider getting RI and then fading away in order to maintain a relationship with your mother. However, this could come with it's own challenges and you will have to weigh the pros and cons of remaining DF vs being RI as a JW.
I faded away about 12 years ago and moved away to another state. I live my life completely the way I want to - celebrating all of the holidays, I have visited various churches, befriend whomever I want, no FS, no meetings, no guilt. It was like a heavy burden had been lifted from me. Since I am out of state, I don't have to worry about watching my back and worried that someone might see me with Christmas decorations or any stupid sh!t like that. If I were DF, on the other hand, I could live where I wanted to live and do what I wanted because I would no longer be considered a JW anyway. I do wonder on ocassion what would I do if I moved back near family. In fact, this is one of the reasons I'm not on Facebook. I still have a fear of being "found out" and then subsequently DFd. I still have a large amount of family in.
Lastly, regarding JWs being "good people". I know how "Society" loves to tell us how wondeful and so much better than worldlies JWs are, but something that I knew even before I faded is this - JWs are no different then average, regular folks. In fact, due to the nature of the religion, I found that in general, JWs were actually less compassionate than average! I remember shortly before my fade, my dad had some serious health issues and I missed some meetings due to spending time with him. When I came back to a meeting, this "holy roller" sister says to me, "I haven't been seeing you! Where have you been? I'm gonna whip you!" I told her my dad was sick, and she said "Oh", and walked off. No "I'm so sorry" or "how is he doing?" or anything to that effect. Never spoke to her again and that was one of the last meetings I ever attended. On the other hand my "wordly" coworkers were very supportive and concerned and happily covered for me while I was gone. I could give many more examples like this.
Sorry for the long winded post! I wish you well in whatever you decide, Stumbeline.
