Boredom. At the very least. He's sentenced her to house arrest, basically. He has no intention of forcing her out of the house on any particular schedule. She'd have to pack before she can leave, for one thing.

He isn't forcing her out, or forcing her in, either way. What he is doing is asserting dominance. He's making it abundantly clear that it's HIS house, now, and that he's going to live in it under his own standards, not hers. As long as that is clear to her, it doesn't matter so much where she sleeps.
