You are NOT responsible for your husband's bad decisions in any way. His decision to do what he has done is his, and his alone.
Your contributions to the marriage are yours, and regardless of what they are, you did not force your husband to go and stick his penis in some other woman.
As for the "fog". I personally don't like that term as a definition for unacceptable behavior in a spouse, however, the FACT of the matter is that people in romantically involved affairs, have their brains awash in a bath of adult level "puppy love". That does result in some pretty stupid (and predictable) behavior patterns from the infidel. When the affair has run its course, and your husband has burned through all the psa chemicals in his brain, he will "de-fog" somewhat, and adopt a more normal outlook on life. This anomaly is well documented.
You have to be the one to decide when your relationship is over and what you are willing to put up with.
All the best, -NOPkins-
I will ferret out an affair at any opportunity.
-An affair is the embodiment of entitlement, fueled by resentment and lack of respect. -An infidel will remain unreachable so long as their sense of entitlement exceeds their ability to reason.
