If he really was her lover wouldn't he come to help Kaguya in her fight? although she was a psycho so maybe toneri thought better to stay out of the way of her way.

not sure really, maybe he had plans of hhis own? for all we know, Kaguya was betrayed by him at some point and that was how she became emotionally distant and cold.
