I also know that women are generally aware of their husbands personal patterns. They also know that if his patterns change, there’s something happening.
The only caveat I would allow is if Sandusky was always having young men and boys hanging around him, prior to her knowing him, because then his patterns would have the normal ups and downs, for him, and she wouldn’t be aware.
But then the question should arise as to why he hangs around young boys so much and not grown men.
As you say...
