I felt like, she may love him, but she is not a pedophile. She knew he adores her, and could make him do whatever she wants, closing him off from the world and making him entirely dependent on her for any sort of human interaction, and since he's a child, he won't know any better and follow her wholeheartedly, happy to be able to spend time with her. But she didn't give into those desperate thoughts (shown as narration in black background)
She wants him to grow, expand his horizons and then come back, so he knows better.
