Well, you know it's not like I stopped believing that it's possible that Heaven and Hell do exist. I can't rule out the possibility, so it's not like I gave God the finger and just went my own way. It's more like I told him that while I think He is very cool, I'm at a point in my life where I need to see other people. I didn't stop loving God, I just started loving myself more than Him, to the point where I was no longer enjoying waking up early every Sunday to engage in His worship. That first martini of the day tastes so much better at 0900h than 1030h, it's a wonder I was ever sober sitting at the organ up in the choir loft.
As far as eternal damnation, the thing that sparked me to abandon my faith was in fact the honest evaluation that if Hell does exist, I was probably headed there, and deservedly so. The choice came down to being a better person overall or just not caring anymore, and when it was that simple, the decision was not only easy but satisfying as well.
