Fuck, I know this sounds horrible but if instead of wanting to fix the marriage she's like "I got a lover let's break up" not even with a Im sorry bro I'm straight up making this a legal hell. This is obviously an exaggeration of reality, as every marriage is a world and maybe the love just died out and he just didn't care about her at all, and just didn't like the feeling of betrayal. But man I don't really like how that was handled, I wanted him to be emotional or something, I get that he's literally an emissary of God in another world and all, and he has all this amazing powers now, but the photo on his laptop shows that at some point he really enjoyed their relationship, it felt just wrong how easily he said "k you can keep all this stuff or just throw it away i don't care"
Really hope the author brings back the wife to give the mc more development, I want to see this motherfucker give a flying fuck about his broken marriage bro :/
