well, he did kiss that girl in chapter 4 and they were hugging, to me that is already cheating...
Oh my bad, I'm stupid completely forgot, but the way they are keeping things ambiguous does make me feel like there's more of a backstory here
I'm starting to suspect that he didn't actually cheat and it's just a misunderstanding? Like maybe the girl got drunk so the husband took her to a hotel or something. Anyways, if he did cheat though she really needs to start blaming him for his actions lol
