He never left her, not even after she stabbed him. He felt like if he left her, he was leaving the final reason to live. Because he is already a blasphemous monster for losing faith.

He feels rather terrified of her, especially because he trusted her. (Still tries to lie to himself and says he still DOES trust her) But he won't ever hate her. Not even resent her despite the fact he BLANTALY told Maveth he will no longer trust her again. He loves her, just not the same ever again.
