Well, it could be due to a lack of communication. If they don't talk about their problems, the marriage might seem doomed. For example, if one person has certain expectations in the marriage like having children or moving to a different place, and they never discuss it with their partner, misunderstandings will pile up and lead to the failure of the marriage.
I haven't read this novel specifically, but from the title, it seems to be about a broken relationship within a marriage and the prediction that the marriage is doomed to fail. Maybe it will explore the reasons for the broken ring, like problems between the couple, lack of communication, or external factors.
The title gives an impression that the story is centered around a broken relationship within the context of marriage. It might show the different stages of the relationship deteriorating, from the initial cracks in the relationship symbolized by the 'broken ring' to the full - blown realization that the marriage will ultimately fail. It could also touch on themes of love, regret, and the complexity of human relationships.
I'm not sure as I haven't read the novel specifically. But usually, in a novel about a marriage in trouble, the main characters would be the husband and the wife.
It depends on what you like. If you're into stories about troubled relationships, it might be. But if you prefer more positive or light - hearted stories, it may not be for you.
I'm not sure specifically as I haven't read it. But from the title, it might be about a marriage that is in trouble, perhaps due to some broken aspect like a broken promise or relationship within the marriage that leads to its predicted failure.
