What exactly is it that Eru did wrong, other than want to marry someone who Loves Him Back?
Belgoat is a place that chips away at Yenni's health unless she touches him, where she's targeted by magic that he can't sense or protect her from, and there are multiple enemies after her (only one of which he knows the face of)...she nearly died a week ago! Why should he let her stay in this situation when SHE DOESN'T LOVE HIM?
If anything, Yenni should make amends for months of lying about her feelings to seduce him. She herself admits that this latest time (chapter 48) is THE FIRST TIME she told the truth about liking him. And it was revelation-coded.

i want her to leave and make him realize all the things he should’ve done and regret a lot, then suffer for a bit till he tries to win her back since now it’s his turn to try and woo her. it’s not that i hate them but i want him to earn and fight for her forgiveness
