I don't think this decision can ever be broken down into pure logic. There are just too many emotional factors involved, and not only our own emotions, but those of others. If I had to start it all over again, I'd have done a few things differently, but I'm not so sure I wouldn't have followed the same overall progression of a "fade."
I would have opened up more to my wife earlier on about how I was feeling and the doubts I had.
I probably wouldn't open up to my parents... I can't trust them entirely anyway.
All in all, I think I faded very effectively. When I realized I had no more faith in the WTS, I knew I had to step down as a ministerial servant. I used my "being stumbled" as a pretext to do so, telling the elders I couldn't set a good example anymore. They came over and tried to "adjust" my thinking, but I steered the conversation clear of any more serious doubts I had. Then, I just started cutting back on meetings, dropped field service, and avoided elders trying to get in touch to "encourage" me. It's been almost four years now, and I can safely say I've faded completely. I only go to the memorial with my wife, and this is the second year I've now gone without attending a convention or assembly. And yet, I have a relationship with my family (albiet a little constrained), and keep in touch with old friends. Most importantly, I've kept the peace with my wife and not alienated her. That was one of the risky things earlier on... and we went through some pretty hard times with our marriage being fairly rocky. But now I feel we see things eye to eye more than we don't, and we're best friends, better friends surely than when I was "in."
I've learned to envision the kind of relationships I want to have with my family and friends in the distant future and make choices that will support that vision. I'm not 100% confident that I'll have everything I envision (having my cake and eating it too), but it's important for me to live my life like I have some control over the relationships in it.
