Re: Gentlemen of Gloucestershire: Chapter 30

Unfortunately, I think GT was more disturbed by the idea of a Mrs. Tilney not keeping boundaries of class for visits/visitors than any concern over straying from the boundaries of her marriage. Regardless, I think the surest proof that Catherine is officially one of the family is that he's treating her the way he does his own children: mood swings, officious dictates, and an expectation of subservience. Not the best sign of affection, but there you go.
