A book about divorce

I'm going through a divorce. I'm hoping to fill the silence at home, when my son isn't here, with an audiobook. I always read/listen to non-fiction, so I'm coming to this sub for suggestions for fiction. I'm a male, 40 y/o. I never grew up around divorce. I have no reference for what the possible futures even look like, and that's causing a lot of anxiety. I'm hoping to find a novel about divorce with a positive theme/ending/spin with the goal of giving my self some frame of reference for this whole experience. Thanks in advance 🙂
