There are many women that are not given a choice, not every woman is in a situation where they can act autonomously within a relationship to a man. This antivaxxer was at least a manipulator and very well could have been an abuser or domestic threat to her, so much that she would not go behind his back out of fear. Her moment of power was at the end where she could finally be honest to him without consequence.

It's shitty that many women live in this world, and your response really shows a lack of understanding or caring.
