Don’t spread your misery to your spouse. Don’t get her worried over you possibly losing your job.
If there is a possibility that you might loose your job, you should share it with your spouse. Otherwise they will be blindsided when and if it happens. If you see a possible emergency you need to get ready, put aside some money etc. Think of Paro’s Dream and the 7 Fat cows and the 7 Thing Cows.
I find that my life is much better when my wife and I talk. And when I have a bad day at work, It helps to talk about it.
