Welcome Skinned Sheep!
There are many reasons why I left. They kept piling up till I couldn't hold the weight anymore and I broke down. Not doctrinal, not pedophilia, not new light, not organisational, not shunning. Many of the reasons are related but none was the actual straw that broke the camels back.
Because of this I was nervous about coming here (besides the fear of "apostates" of course!) because I didn't want to latch onto someone elses very emotive, heartwrenching and personal reason for leaving and make it my "justifiable" reason for leaving. So I mainly read individual experiences - with increasing amazment that my basic story was repeated so regularly (me - born in, left school to pioneer, married a pioneer, MS, CA parts, etc).
I'm glad I did this as the space allowed me to identify who I am.
As time has progressed I am now getting interested in the doctrinal etc stuff. Purely as an intellectual exercise but I also feel some therapeutic benefits as it has helped to recover and consider a lifetime of repressed questions, feelings, thoughts and memories.
I'm glad that your wife is out with you, my amazing wife is all the way in and is torn in two. The last 6 months have been the most terrifying, amazing, hurtful, rewarding, frustrating, relieving, destructive, healing and so on ad nauseum, time in my life, particularly for my marriage. There have been many days where we have ended up closer than ever in understanding each other but only hours before we had been seconds away from all over. Add the other usual things that cause stress on marriage (finances, work, parenting, illness, etc) and there are some difficult stretches.
My wife sometimes pines for the "good old days", when we were just "happy'. On the stressful days, I understand her sentiment. From another angle, my determination to question and examine every premise has allowed us to make some massive breakthroughs on small but ever present issues that have arisen periodically during our marriage. Where will it lead? Only time will tell....
I hope you can find support that is practical and helpful to you and your wife on this forum and look forward to reading your thoughts/questions/perspective on the many and varied topics that are discussed.
Cheers Ob.
