So did the mother know or not?

How could Susie's mother act like her husband did nothing wrong?? She seemed to love Susie, but at the same time she appeared oblivious to her husband's past offenses.
I think she knew, but was having one of the weirdest cases of denial I'd ever seen.

What do you think??
