When the Church decided it didn't need me any longer, and I decided I would get on with my life without involvement in the Church, an amazing thing happened. I made friends with non-Mormons. Lots of friends. And it wasn't so I could ask them "the Golden Questions". And it wasn't so I could invite them to church and send the missionaries to their homes. It was so I could get to know them. We went places together, two at a time, ten at a time, and did things together - fun, crazy things, and traditional things (Rock Opera). The world is bigger than Mormon and non-Mormon. There are all kinds and sorts of "greys". The world is not black and white. Not just black and white. And the greys. They aren't grey. They are every color of the rainbow. But I couldn't see that before, when I was wearing my Mormon spectacles all the time.
The best thing for me, in disassociating from the church, was getting to know people as people (not as potential proselytes).
The next best thing, was taking a few steps back, and looking at Mormon teachings from outside the Church. And looking at what different people believed without judging them according to Mormon standards. I was "between standards", so this more objective looking at different religions, philosophies, teachings, I think it all helped me to settle in on a belief that has been evolving over the years. The one thing that is maintained is that there is no "only true church" - and maybe it doesn't matter so much what you believe about the hereafter, as much as it matters how you treat people in the here and now.
