Genuinely not intending to be petty and argumentative here, just to be clear. It's just that I disagreed with what you initially said:
Her reaction was far more akin to someone who felt their husband had just slept with another woman than someone who'd been caught with a sex doll (words he used himself and she snapped at). She saw it as cheating, and you can't cheat on someone without another person being involved so in that moment (and thereafter), she'd humanised Anita as opposed to viewing her as an appliance.
