Why would I have to go back past the Watch Tower CD to prove them false? If a Witness will not be impressed with the dispensing with the sheep and the goats separation teaching, the generation of 1914 prophecy (Creator's promise), the loss of government neutrality with the compromise on military service, and the United Nations NGO association, and the allowing of blood products, I'd say they will never be impressed with older books and they will probably never be impressed at all.
Most women Witnesses are social Witnesses and not scholars.They go for social reasons usually because those social needs and not being met on another level.
All Witnesses are Witnesses in spite of the error and the problems. They are mostly aware of them. They aren't Witnesses because the Witnesses have a long history of being right. Anyone who has been a Witness for a few years has seen multiple changes. Those changes were the admission of error and the new teachings are regarded as temporary by the Witness people and subject to being changed without comment or problem.
I think all Witnesses issues in a marriage is a marriage problem and not a religion problem. For many of us, to deal with it on a religion level is to mess or miss an opportunity.
Is the marriage satisfying and rewarding? If it is, it's satisfying and rewarding WITH the Witness element as one of it's parts. If it's not, then THAT should be the issue. Group association may just be a symptom. Some of us found good results in consulting with a rational, objective, competent, third party.
There's an incredibly good chance I don't have any idea what I'm talking about.
