What kind of traps can a mistress set so the wife can find out that her husband is still seeing the mistress and doesnt want to stop?

This is just wrong and you are just as in the wrong as the husband. The best thing you can do at this point is STOP SEEING HIM it is not up to him to continue the affair!!! If you feel the wife should know you could call anonymously and tell her or be up front face what you did and tell her directly from you. There is no since playing childish games and "traps" or whatever you want to do this is about people's lives and it is just wrong to think of playing games with them foolishly.
