On the other hand, if we look at it from a more metaphorical sense, like sharing a partner's experiences or feelings. For example, a couple sharing their relationship journey on social media. It can inspire other couples to communicate better and be more open in their relationships. But this is a far cry from the traditional concept of wife - sharing in some stories.
It can have a negative impact. In modern relationships, which are based on monogamy and the concept of individual privacy and commitment, stories about wife - sharing can seem very alien. It may make people question the values of loyalty and exclusivity in a relationship.
