Yes, the Beast changed.

He spoke more now, and did not gaze at Beauty in the same intense, almost pained way, as if he were feeling every emotion she felt. He did not sigh in his sleep when she sighed and his stomach didn't growl when hers hurt. He could not read her thoughts anymore, and she could not read his. He seemed a bit more clumsy and guarded and distant, too. They no longer ran through the woods together, although they still walked there sometimes. They quarreled and raised their voices to each other once in a while. Each time, after they quarreled, Beauty bathed, combed the tangles from her hair, and began to wear shoes again for a few days.
