Alien,
Oh dear. You don't have faith in your wife.
You've tried and failed with that schtick before - conflating the ambiguities in the term "faith" and then pointing to the presence of one as if it were inconsistent with denial of the other.
The prosaic meaning of "faith" is a reasonable confidence of a future event or behaviour based on the evidence of historic data. I have "faith" that my car will start for example the next time that I want it to - it's a good car, it's well maintained, it's aways started in the past etc.
The religious meaning though is very different - it's the bridge you need to build from assertion to belief precisely when you
don't have evidence to support you but want to maintain the belief nonetheless.
Most of us have "faith" (first meaning), only some have "faith" (second meaning) and treating them as if they were the same is just cheating.
Again.
