I've read portions of that book, and the description is not inapt. It's a man of late middle age explaining to his young (14 iirc) wife _every painful feature of her duties_ in excruciating detail and with perfect self-concern, in a way that is not typical of the way wives are addressed and marriage handled in other works I've read from the time. I found it hard not to dislike the author intensely, which was not my reaction to other medieval writing at all.
