Basically the wife got fed up cuz he was way too passive. She felt like he didn't care if she was there or not and when she walked away, he didn't stop her
dont remember what she actually is (a demon or something supernatural according to a spoiler. been a while not entirely sure) but the recent chapter really highlights how she doesn’t understand human relationships bc she isnt one herself.
