I'm going to lie to my wife
Why do you need to lie to your wife? Are you hiding something?
Of course. I'm having an affair.
It is not ok to lie or to have an affair. You need to come clean and try to save your relationship.
It's all part of my plan. I want to see how long it will take for my wife to find out. I want a divorce anyways.
It is a bad idea to lie. In the long run when you divorce you will look really bad to the courts.
