Hermione doesn't know why, and she tries to tell herself there could be reasons, and that he might not have abandoned her, betrayed her, or been killed. She isn't sure if she believes the excuses she makes up for him, though. Perhaps she is just fooling herself, and she is on her own. It doesn't matter, she decides in the end, with her hands balled into dirty fists in her lap, her hair stringy and lank around her face. All she can do is focus on staying alive, until Malfoy comes through or the Order rescues her. Because they will, she tells herself. They will. Hermione refuses to die here, like this, starving and weak and forgotten. She will survive, no matter what it takes, no matter what she has to bear, no matter how much it hurts. Hermione Granger is a survivor.
