She might simply be a person who loves diverse stories. Black men's stories can range from tales of family, community, to their own personal growth and development. By being exposed to these stories, she can gain a broader perspective on humanity in general.
Suggest watching documentaries or movies that feature black men's stories. There are many great ones out there, like 'Hidden Figures' which showcases the important contributions of black women and men in the space program. You can watch it together and have discussions afterwards.
You could also try to get involved in these interactions. Join in when they are sharing stories and see what it's all about. This way, you can better understand the dynamic and your wife's intentions. If it's all about positive cultural exchange and friendship, there's no need to overreact.
This statement is rather unclear. If by 'use her stories' you mean share or be involved in her personal anecdotes, it could imply that she enjoys a diverse social interaction where black men are part of sharing and engaging with her life experiences. However, more context is needed to fully understand.
This is not normal behavior at all. In a committed marriage, the focus should be on the relationship between the husband and wife. Having an interest in such stories involving other men is concerning as it goes against the loyalty and exclusivity that marriage typically represents.
This kind of interest is not in line with the norms of a healthy relationship. A good marriage relationship should be built on positive emotions, common goals and positive communication. You can try to introduce some positive literary works or movies to your wife to guide her interests to a more positive direction.
There was this time when we were having a picnic. I had made a homemade pizza. My wife started eating it and she loved how the crust was crispy on the outside and soft on the inside. She ended up eating most of it while chatting about how good it was.
One possible story could be that they met at a multicultural event. They discovered a shared love for art and started chatting. Over time, their friendship grew into love as they explored different galleries together and learned about each other's cultures.
