I'd care if it were me though. Not for anything but the likelyhood of survival. FL got offed already and he's refusing the divorce. If using rumors of being blemished is out then the only way left is to not make offspring for him to think she's unable to get pregnant. His personality is bad and he's totally a dangerous person to be around.
You got a point in terms of survival yes, but to me it seemed like she cared about his opinion too as a potential love interest (hope you get what i mean)
also yeah, he truly is an awful person, i mean, he's literally the one that treated her badly yet he is the one to hold a grudge? Honestly i couldn't bring myself to like him
he is the one who cheated, why the heck would she care if he holds a grudge or not? He can stay with his two-faced concubine, they match each other.
