You have my sympathy, this sounds like my wife and circumstances. I could never love a woman who squealed on me for reading a book to see if our child's rape was a common occurrence in the WT. I have a degree in Psych. You have virtually no chance of having a healthy marriage with this woman. Any love you feel will have "strings" attached to it forever. I would fade, divorce her (after considering what's best for any children), and move on. If you stay with her, you'll hate yourself forever.
I'm sorry to be so blunt, but even the back scratching sounds familiar. She is using you and dictating the terms. You simply can't let that asshole elder treat you like that. God, I can't believe how F***ed up these people are. They all need to be in one large asylum. Call your wife's bluff. No sex, no affection, no meetings, no study. Did she love and marry YOU or a male JW? If she chooses the WT over you, then you have your answer. I loved my wife too, but lost respect for her and me when I tried to go back to the meetings after quitting when I discovered the child rape policies.
Good luck and I hope you do well.
