You could start by having an open and honest conversation with her. Express your feelings calmly, like 'Honey, I notice you go out with coworkers a lot, and sometimes it makes me a bit worried.' Then listen to her side of the story. Maybe they have important projects or just a friendly social group.
One way to build trust is to involve yourself in some of her work - related social events when appropriate. This way, you can meet her coworkers and get a better understanding of their relationships. Also, focus on strengthening your relationship in other aspects, like going on dates regularly, sharing your daily experiences, so that she feels more connected to you and is more likely to be trustworthy in her outings.
There are also stories of coworkers helping each other out in personal development. A coworker of mine noticed that I was struggling with public speaking. So, she organized a small group within the office where we could practice presenting in a friendly and constructive environment. Through her initiative, I became more confident and better at public speaking.
One story could be that a wife goes out to explore a new city. She visits local markets, tries new foods, and meets interesting people along the way. She might discover a hidden art gallery and spends hours admiring the works of local artists.
It depends on various factors. In some cultures or regions where the climate is warm and the lifestyle is laid - back, it might be more common. For instance, in beach - side communities, women often go out in simple dresses to run small errands or meet friends.
Perhaps the wife goes out to a local fair. At the fair, she strikes up conversations with other attendees while looking at the various stalls. She meets a group of women who are also interested in handicrafts, and they start sharing tips and ideas, which eventually leads to a new friendship.
Most of such stories are likely fictional. In a proper work environment, such behavior is completely unacceptable and would violate many laws and ethical norms. It's more of a disturbing and inappropriate fictional concept that might be spread for shock value.
It depends. If your wife has a healthy relationship with you and is just having some time with her friends, there's usually no need to worry. It's normal for people to have a social life outside of their marriage.
