Hi,
My situation is that I studied but never joined.
I'll interpret Q2 as "why didn't I 'progress'"? Because the literature presented as "Truth" wasn't true. For example quoting Francis Hitching; even citing him as an authority. He has a basic science degree and has never worked as a scientist; the simplest Google search establishes this. And pointing this and other concerns out got me labelled "opposer". Any information that didn't fit was managed by bad-naming the source; a simple logical fallacy.
I do feel some bitterness as I saw my brothers' marriage to a jw struggle and finally break, and what their children went through. I saw that both parents tried their hardest to maintain the marriage but the jw religion doesn't allow compromise.
