I'm secretly binging snacks by myself and replacing them with the same amount left so my spouse doesn't notice I am pigging out.
It doesn't sound reasonable to do that. Why are doing this?
I don't want them to know that I'm eating too much.
Binging on food like this is really unhealthy. You shouldn't hide that you do this from your partner, they might give you motivation to stop if they knew.
Nah man, I like the food so much that I want to continue with this for a while.
Well, I thought you wanted to be able to be honest with your spouse?
