I couldn't agree more. Basically, if he's insecure about himself in this other relationship, then it's his responsibility to confront that issue. If C is insecure than it's her responsibility to voice her concerns and do her own self-care. If this other woman is such a potential threat, then like you say, maybe he's better off staying away.
For me, as more of an exhibitionist, I don't think it would be much fun being watched by someone who's bored out of their mind. I wouldn't take it personally or think that it means I'm boring, but I would probably get distracted if their energy was completely messing up the scene.
