Its amazing how a perspective can change with a bit more information.
When I read your initial post I was like: give him a chance to work through the difficulties of leaving home and finding independence away from his parents.
But 32? 32 years old!! And still living with mummy and daddy?.... well that did it for me; this guy is financially dependant, a man-child who is by the sounds of it a male chauvinist just like my brother and father.
Make no mistake, they're good at hiding their misogynistic personality but it will surface when they feel comfortable doing so.
And as you said they have no qualms about lying.
You'll find men like that from all walks of life, so this can't be solely blamed on the cult, it's part of his inherent personality.
If he truly believes the cult indoctrination and refuses to research ( togther with you ) the child rape crisis and other Jehovah's witness related issues, then he has no business being in a relationship with anyone outside of the cult.
Indeed you have dodged a bullet.
And I would advise you to stay away from anyone who refuses to have their beliefs challenged and scrutinized.
Sorry you had to go through this, but it's better than continuing such a relationship.
Best of luck for the future.
