Just as I thought. He loves her at first but she sees him as "I could've married with anyone even if it's not you and be like this" if I hear that I'd be very empty and dirty. Like am I just another empty person to you? Do all humans look the same to you?
All he wanted to hear was probably just "I'm glad to marry you, I'm glad that you're my choice"
She wanted to be understood without saying a word, but she also didn't try to understand him.
Just because the story so far is from the female's perspective we can't just support her without considering the male's point of view.
_My comments from chapter 22_:
Well, the the couple had it rough. We all know how hard the female endured, but if you also look at from the husband's perspective he was also young and had to go through war.
He also had to succeed the duchy plus fighting his greedy family as soon as he got back from war so of course he'd be pissed. He was really busy to managed the duchy...
The wife was depressed cuz she lack comfort, while the husband was annoyed and angry due to his relatives.
_end of my comment on chapter 22_
And now I am convinced that this author made a gold like story

Complicated humans
Well, it's normal to have this unhappy marriage. If you asked parents if they still love each other, most of them would likely only stay together for the kids.
While in this story they stayed cuz it's already done (married) so they just live forward without trying to harmonise. I mean, they just stayed still and only have a real conversation now.
Well, as long as they're not dead yet one can nvr be too late to fix a relationship :)
