Who says that? He’s a normal person being scared that his wife isn’t who she says she is. It’s like a horror movie lol. He obviously prefers he new personality, he said that before. He’s just anxious and scared when this stranger in his wife’s body is lying to him.
No sane person would calmly accept that just cause the new personality is nicer. For all you know the new person could be a demon with dark intent LOL

He got a better wife and he’s questioning her unusual change….does he want her back that bad??
