She wanted to be punished that's why didn't want to tell him the reason. Also, she doesn't really have much faith in him because he never shows that he cares. I'm not sure if it was ever explained here but he knew that the servants were not respecting her. He just didn't know the degree. But the fact that he knew but he brushed it off makes my blood boil.

And to be fair, she wasn't really given a reason so far to prove or explain herself. She grew up with people not listening to her, accusing her despite her trying to explain herself. Even when she got isekai-ed here, it was the same. It will really just become tiring to be repeatedly accused without people trying to hear you out. Don't worry though in the future she'll try that again and guess what, it will be in vain again.
It’s starting to get a little frustrating on how she never explains what happens and just automatically says “I’m wrong punish me.” Like obviously the story is changing so I don’t get why she just doesn’t tell him the truth. I mean she’s expecting to get punished either way.
