I’m not sure but it could be because she experienced her family’s abuse herself while she experienced her husband’s neglect primarily through someone else’s memories
He's has done enough upon repossession to still be on the naughty list. She didn't even get mad about finding out he knew so much about her past and present but did nothing, yet her brother's similar indifference to her abuse got her that hateful. The math is not mathing.................but there is a chance she feels like her possessed actions warrant it from him to an extent whereas her family bullied her, as an innocent child
Why does she see the men in her blood family as disgusting hateful vermin, but she's always only mildly disgusted by and impartial to her husband who is literally just the same??? This double standard feels like a major plot hole to trick us into them falling in love later on. He didn't do much to her since she possessed this body, and I appreciate they spent the whole first season really showing you how he treats and thinks nothing of her. But that awareness of his trashy character is completely canceled out by the fact the MC doesn't care much.
