Not at all. Ethical behavior in a relationship involves treating the other person with dignity. Revenge stories often involve actions that can be cruel and vindictive. It's much more appropriate to handle relationship issues through positive communication channels, or if that fails, through legal and respectful means like divorce rather than revenge.
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.
Revenge is never a healthy option in a relationship. Instead of seeking revenge, communication and understanding should be the first steps. If there are issues in the marriage, it's better to have an honest conversation with your partner or seek professional help like marriage counseling.
Rather than focusing on stories with inappropriate labels, we should encourage positive and respectful relationship stories that uphold equality and mutual respect between partners.
I'm not sure specifically as this is a rather unclear title. It could potentially be about some fictional or real - life relationship situation that has a negative or complex connotation, but without more context it's hard to say exactly.
Most likely not, given the use of the word'slut' which is a derogatory term. But it could be a story that aims to subvert that negative connotation in some way.
