Hey man, congrats on your bravery and free thought, I am sincerely impressed by your inner strength, knowing what it takes to dare to even doubt.
you can make it very easy on yourself and your wife. The Watchtower literature have sold you a god, it's a fatherly, warm, loving God who cares so much for you he even notices a leak, amongst all of earths goings on......etc etc etc... He cares when you are financially broken, when you are emotionally exhausted and when you are physically ill.....
The best thing I ever did, was read the bible, from scratch.... I mean, not in a robitic JW way with a JW focus on specific sentences, ignoring the rest, but reading it as you would read literature, a book. I STRONGLY recommend it.
By by the time you have read a few books with continuity and context you will see things you had never ever seen before, things that will make you realise the bible tells a very different story with a very different God, a very, very, very unpleasant deity.....
trust me, the good book will sink the nails in the coffin itself,,... You have to love the irony
