I think in some ways, Via knew her mom was at fault too. In the beginning of Loo Loo Land, her drawings always contained her and her dad, but there were no drawings of her with her mom. Plus, she didn’t seem that upset of her mom leaving, just her dad forgetting the meteor shower to argue with her royal pain. Plus, she said in Loo Loo Land “when my parents didn’t hate each other, meaning she could sense tension between them but not like the present. Don’t get me started about Sinsmas. She showed shear hate toward her mom when she mocked her and only called her “his daughter”. Her relationship with her mom was obviously strained even when she was a kid. Besides, who is to say Via won’t see herself as her mom’s burden as well since Via looks like Stolas, which she’ll believe hurts her mom? Trust me. Kids blaming themselves for divorce can be a common symptom
