What do you think about me not telling my wife that I was laid off of work?
It's wrong to keep that from her. Why aren't you going to tell her?
My wife has been spending too much of our money. If she finds out I've been laid off then maybe she would stop.
Lying will only delay the problem. She would expect you to get a new job. Then the spending would start again.
Nah I think it's better just to keep lying to her.
It seems you are also concerned about your wife's spending. If you tell her the truth about being laid off, your wife will spend less and you won't have to worry about concealing this information from her. It would be wrong to lie about this major thing that will affect your stability.
