Juliet writes to Sidney and says that earlier, she and Kit took a picnic to spy on Dawsey while he rebuilt a stone wall. Dawsey then invited Juliet for dinner. It was awkward at first; Juliet perused Dawsey's bookshelves while he cooked. She found Anne Brontë's novels and her own biography of Anne Brontë. They discussed all manner of things over dinner and after, Dawsey showed Juliet his pigs. Juliet admits that she's completely in love with him.
Even if dinner was awkward, it did impress upon Juliet that Dawsey is a person she could spend her life with: he has lots of books and must respect her career, given that he owns Juliet's own biography of Anne Brontë. This indicates that he wouldn't try to stop Juliet from writing if they were married.
