Ok, but why doesn't she tell riftan about the abuse(I just genuinely want to understand her thinking), he is reassuring her a lot and showing her love A lot, and there is still no communication. It feels like we are marching at on place, never moving forward no matter what the people around her do or say, to make her feel loved(because a lot of the servants do, even the princess). She just doesn't trust them, doesn't budge, even though they are so kind and loving to her. What is stopping her? Scared to be judged,.... of what, if someone does this to some random woman, she knows it's wrong, but when is about her it's shameful??? I don't get it.
Because she thinks it’s shameful. She doesn’t know Riftan has loved her loooong before she met him at their wedding. In her POV, she knows her father gave Riftan and the knights a seemingly impossible task and, if they came back alive, Riftan would be rewarded by marrying one of his daughters. As if it’s a great prize but she, being the sister who is abused, stutters, isn’t beautiful (according to her father), untalented, etc., she feels that it’s almost pitiful that he has to end up with her and not someone greater seeing as he’s this incredible knight. A knight sooo incredible even the king wants him to marry his daughter. But, instead, he ends up with her.
So she keeps it to herself so he doesn’t learn how unworthy she is for him. And he doesn’t let her know about how hard he fought because he WANTED to marry her. His POV is she was unlucky enough to have to marry some brute she doesn’t know as the rich daughter who was doted on by her father (because the rumors say her father treats her incredibly well which we know is a lie but he doesn’t).
So it’s a lot of miscommunication between the two because they don’t want the other to know how unworthy they each think they are for the other.

If you’re coming to the comment section to call Maxi a moron, say she deserves/wants to be abused, or to talk shit about her instead of her father for abusing her, you still have the opportunity to turn back and keep your misogynistic comments to yourself. :) Just count yourself lucky enough that you don’t understand and can’t empathize with an abused woman’s experience. Her trauma isn’t going to go away from the months she was away from her father when she lived her entire life fearing and being beaten by him.
