Yeah, i understand her circumstances but it could have been solved, if she just had a conversation with him, it's not easy for him either, and constantly accusing he has a mistress when she herself cheated on him, yeah I don't like her one bit (but she's a well written character), I am only going to read this for the ml and she knows what kind of marriage she had, he wasn't the best husband but he did try.
I mean.. "He did try" did he ? Did he really? his communication is quite literally just as bad as hers (he openly admits at first really until recently all he did was basically pity her) - she locked herself away in her room (for the most part) and he locked himself away in his very being. Giving her 'stuff' doesn't really .. do or change anything.
She thought* he had a mistress, he did .. next to nothing to dispel that. He allowed open rumors to run wild in his own domain (heck in his own 'house) unchecked , unchallenged.. slander unpunished. The real honest truth is the both of them sucked first TL wise.
Also once again bare in mind that she was at max 10 years old when she was separated from any family she had that might care or value her (Father being removed since well he never did).
Then she lost her care taker which was the only 'family' she had left.
Starting anything like that will be very... awkward to put it mildly Her being an evil wife and throwing tantrums.. more then half of the images we've seen are her 4+ years ago - doing that math isn't hard.
As for the simple idea of a 'conversation' solving all these issues... well shes had several with him now and hes at this stage still mostly closed off most of the time. exceptions are growing (next chapter should be their first real elongated conversation) but she was two things in the past time - scared of him - and thought he was already with his mistress so..
shrug basically yeah they both were moderately useless in the first timeline hell he didn't make sure his domain/fief would be properly* looked after if he fell in combat. (Speaking to the king which a count can request especially one of his 'fame' might have made things protected or handled in a different succession line - but he uh just rode off to war mindlessly lol)
But yes I obviously know things change even how they change but just figured id note it for the hell out of it.
