A true friend is someone who allows you to safely strip away all the masks and knows you, your very true essence, accepts and loves you.
Your wife sounds like the very foundation of the WT cult, she's abusive. It seems impossible to have a true friendship with a fully indoctrinated cultist if they're ultimately going to cut you off if you don't believe their "God" aka 7 leaders or their man made controlling abusive rules.
The difference between a real friendship and a cult friendship is the difference between planting a seed/watering it/exposing it to sunlight/watching it bloom into a flower versus sticking a shiny plastic flower into the grass.
