@naomi you just answered your own question. SHE CHANGED. Simple as that. He hated how she was acting previously. And even when she changed he still couldn't fully trust her. Like you would had you been in his position and went through what she put him under. If she had remained how she was, no one in their right mind will want to be near you. But when someone changes GENUINELY, of course you'll want to interact with this person. That is basic common sense, even in real life.
