Hey fairchild, it sounds like you are on the cusp of making an important decision. I hesitate to give advice because so many factors need to be taken into account when deciding to discontinue one's involvement with the JWs. Having said that, and given your own expressed sensitivity to how you might be viewed by the JWs, I'd recommend the slow, fading exit, because JWs sadly would not reciprocate any courtesy you might extend in explaining your situation. You don't need to spell everything out to the JWs; that's what I call playing "the explain game"in which the more you explain, the more puzzled the JWs look and the more deeply anxious you're likely to become and the only outcome is a variation on being rejected and condemned.
Always remember that you are an adult and if you chose to stop going to meetings, that is your business. Little by little, as more time passes and you learn to relax the need to have everything crystal clear in the doctrine department, you'll also become clearer about what you want to do in your life. It will be a painful process, whichever way you decide to go; view the pain - which will pass - as necessary to your personal growth. I always remember what an old colleague said to me a few years ago when I faced "decision time". He wrote: "Which ever path you take, whether to go or stay, there will be pain. You have to allow yourself the time to weigh up which course is going to be better for you in the longer term. No one can decide for you but your real friends will be able to support you in that decision." Fairchild, I wish you well.
