Well, I wouldn't say I went through gehenna to get out, my gehenna was my first marriage. As stressful as the divorce and leaving the religion was, it was still better than being married to the wrong person, that will just suck your soul right out.
My leaving the religion was a long drawn out affair, the last ten years I was mostly inactive but attended meetings. My ex was disfellowshipped, my children not interested, I don't know what stubbornness kept me going, just fear of the unknown I guess. I finally became a stronger person and started to realize their was no reason to stay in a lousy marriage and a religion that gave me nothing back either. I knew I had to get out of the marriage at least. A chance encounter (online, nothing naughty, classmates.com) with a guy I knew in high school gave me the kick in the pants I needed to cut the cord. I asked my ex to leave and started making plans within the week. He was not surprised, he knew I was done, he had many opportunities to improve, I believe he wanted me to be the bad guy. I also realized the Watchtower had given me really lousy marriage advice and that was the kick in the pants to ditch the religion as well.
A funny story about my ex that will give you a glimpse of why I left. The day he moved out I was really sick, a high fever, shakes, etc. As I lay there in misery he comes up to me and says "There's no clean towels!" I lifted my head off the pillow and just looked at him, he, not taking the hint said "What will I dry myself off with tonight?" I was too stunned to say anything. Lord help me, did a grown a$$ man of fifty just ask a sick, soon to be ex wife to wash his towels? The divorce was final in early July and it was really independence day for me.
Despite some nastiness from him, It went pretty smoothly after that, sold the house, wrote my JW mom and told her the news. I thought she would be upset but she never thought I was a good enough JW anyways, so she took it pretty well. Within months months I got a job transfer and moved out of state to be with my high school friend, we've been married fifteen years now, very happily I might add. Yes, there were transition issues, it's very hard to make huge changes in your life like that, but everything worked out.
Some want to take the band aid off slowly, but by bit (fade) but I ripped that sucker right off, a big dramatic, no turning back statement, which was the right choice for me. I never DAd or anything, moving out of state makes it hard for them to df you, although my JW family still treats me as if I had, but yes, it was totally worth it.
