I recommend the novel "Top Fighting Techniques at the Beginning of Rebirth". The skills of a cheater would allow you to not lose money when playing cards, but at the same time, it would also make people worry that they would lose their hands one day. The storyline was also full of elements of starting over and pursuing the hero's dream. It was very exciting. I hope you like this fairy's recommendation. Muah ~😗
There are no ethical or positive sites dedicated to such stories. Cheating is a serious and often hurtful topic that should not be exploited for entertainment. Instead, you could focus on reading relationship advice or self - improvement books that promote healthy relationships.
I once knew a student who cheated on a math test. He wrote formulas on the inside of his water bottle label. But the teacher noticed he was constantly looking at the bottle in a strange way. When the teacher checked, he got caught red - handed.
Another option could be Archive of Our Own (AO3). It's a large fan - fiction archive. There are a lot of different story categories, and some of them might involve stories about cheating wives. However, it also contains a mix of different types of content, so you need to search carefully using relevant tags.
