I read that they're a very religious couple who hasn't been intimate, even though they're living together. Adds a weird twist in my mind. While I think 32 is old enough to have handled this properly, I wonder what sort of prewedding panic might have been inspired in someone whose own mother described her as needing to quit work and be a full time mother. (This is what I heard on the radio this morning, and think the source was New York Post.)
I would be hesitant to ascribe any of her odd behavior to religious choices or abstinence before marriage as plenty of religiously-observant people manage to get married or even call off marriages without involving the local authorities.
