I don’t think people here took screenshots of her dad’s tweets but he is a piece of work. I do think he’s that typical boomer who was rather harsh with his words. For those who missed the tweets, his opinions are very similar to Gabbie as they tend to be elitist, narrow, negative, with a touch of racism/sexism. Her dad is also the type to push his opinions on everyone within earshot. Gabbie’s behavior on social media is the same. She truly is her father’s daughter no matter how hard she tries to be different from him.
Based on this, I do think that he has said some nasty things to his children/wife and Gabbie is allowed to resent that. I do however believe that Gabbie was a difficult child who acted out when she didn’t get her way and her dad didn’t tolerate it so she hates him. Before, Gabbie also alluded to the fact that she also resented Jane but now is besties with her not because she matured like how most kids get on better with their parents when they reach adulthood, but because Jane gave up and just pandered to her spoiled child. Jane knew Gabbie had no one and cannot function as an adult so she became a doormat. This is why Gabbie likes Jane now. Her dad never buckled so he’s the enemy.
