Look at Carmella Soprano and the other wives on The Sopranos. They were willing to turn a blind eye to an awful lot in order to maintain their lifestyles.
I wasn't a regular viewer of the Sopranos, but I know that Carmela left Tony for awhile because she finally got fed up with his affairs. She ended up dating her son's teacher. Of course she did up getting back with him before the series ended, so I agree with you. She definitely wanted to maintain the life she was accustomed to by being married to him.
