The story of Adam and Eve in the Bible is a classic example of betrayal between a couple. Eve betrayed Adam by eating the forbidden fruit and disobeying God's command, leading to their expulsion from the Garden of Eden. Adam, on the other hand, betrayed Eve by blaming her for their actions instead of taking responsibility for his own choices. This betrayal between the first couple ultimately resulted in their separation from each other and a loss of the idyllic paradise they once shared.
