At at even more unbearably boring than usual Tuesday night meeting I decided to read the book of Romans from start to finish as something to do.
I had never read anything form start to finish before as I found there was never time to actually read anything besides the singles verses chucked around here and there, although JWs are meant to do their own bible reading I found with a full time job, 3 meetings a week, prep for those meetings, FS and all the other stuff to do I had zero free time, and if I did it was a saturday night at which time I just wanted to chill.
Anyway, I read it and all and what I read didn't gel at all with the 'good news' JWs preach. Actually it seemed very loving and basically said 'try your best'. At that point something clicked.
For years I'd put up with people acting badly, putting it down to imperfect behaviour, same for the obvious lack of love. Lots of things doctrinally didn't make sense, but I shelved them.
I think reading Romans along with also studying the Revelation book at the time, where it was obvious the WT had no idea what it was talking about, made me realise JWs didn't have the truth at all.
I was set to move congs as had just got married, missed some meetings due to the wedding, then honeymoon, then was ill for a bit - it resulted in about 6 weeks away and enough to shake off the brainwashing.
I looked into some of the doctrines in more detail, which ended up in proving to myself that the whole thing was made up, and then by extension realising that the bible was just as made up, and ended up agnostic.
