She did not trust Draco. What if he was planning something and simply wanted her out of the way? She remembered that dark, confident demeanor around him while Hermione had been in that strange, spelled sleep—she’d known he had wanted to make Horcruxes for the both of them but had not thought he would do it until Hermione was awake again...a naïve thought. And when he'd told her he'd done it, she knew there was nothing she could've done to stop it, but still couldn't help the guilt she felt over it, as if she'd somehow betrayed Hermione.
