Help me prep for an upcoming argument

[CodependentHusband]

One of the struggles I had, which I feel I have come to terms with, is that there are certain things I will not share with my wife. All of the details concerning my purchases for other people while I was on a business trip may well be one of those things if I were in that situation and it was clearly triggering to my dBPDw.

On the surface, it would seem that I would be lying by omission. And, let's face it... .  maybe a white lie like that runs much deeper than the surface. My wife has a very real mental illness that affects her cognitive abilities, and she is hurt very easily! I can dillute myself by thinking, "I am compromising MY integrity by witholding information from my wife," or, I can whole-heartedly accept her mental illness and realize, "my wife's condition does not allow her to accurately process certain information. I will protect her sometimes by not providing her with information that will cause her to worry needlessly. If my wife were mentally healthy, I would love to be an 'open book' with her 100%, but she is mentally ill. I and duty-bound to protect those that I love, and I will do it for the betterment of my relationships."
