Well she might have in the anime. We have to remember that the wife is an anime original character. They also changed a lot of plot points in anime.
IE Souju wasn't that tragic of character in the novel as she was actually treated decently (beside living in seclusion) by Kuhouin family. She was portraited as wise and considerate rather than just a weak women who would take whatever thrown at her. Also, Shinkuro has a somewhat violent temper, and actually perfer to resolve things with violence(!) if it appears to be the most effective/direct way. He's FAR from the Mr. nice guy we see in the anime.
That being said, I actually perfer the style of the anime instead of novel though. The characters in novel just felt too damn cliched. Not to mention Murasaki in novel actually feels a lot more annoying than her anime counterpart, too many typical moe craps she does in the novel.
