Working through the sidebar with NMMNG and MMSLP, but am in a situation where I need an answer on how to move forward with something and am not sure how to proceed?

I messed up and got caught in a lie with my wife over something stupid. I spent money on something for myself and she found the receipt. To make matters worse being the typical nice guy I tried to lie about it.

It basically ruined Christmas, we have not really spoken to each other since Sunday. I don't want to give in and hand her all the power back, honestly I make good money and we are not struggling financially I should be able to spend my money on myself If I want, but the cover-up and lying made the situation worse.

Do I apologize for the lying or just continue to wait her out? I know I was wrong but don't feel sorry. I know thy lying was wrong and not helpful to the situation but I want to avoid losing more face or doing anything further to make her feel in control.

I am sure I will get destroyed posting this but any advice however harsh will be appreciated.
