He probably could have refused. But by marrying her he also got her family's support for him to become the successor of the duchy. He was ambitious and wanted both the power the family could give him (at first) and his lover. I mean he ain't good either.
From spoilers he seeked her out to use her and strengthen his position, he tricked her into becoming attached to him and marrying him, cz she had gem mines in her name and her family name is very strong
Yeah and then he behave as if she's a parasite... Smh
i don't believe he deserves a redemption arc, and i don't like how they make it so he liked her after she changed as if it was her fault how he treated her before she 'changed' as if he isn't an opportunistic ahole
Imagine you help a woman one time and then she clings to you. Breaks off you and your fiancée's engagement. You have to forcefully marry her. Have sex with her.
Like damn I would be fcking pissed.
It is sad about what happened to her but it does not mean she could do that ¯_(ツ)_/¯
