I really don't think in Cemar's case his helping or not helping is significant. I think Crazy Eddie got it right that Cemar just recognizing and complimenting her hard work would be worth a lot more. HE does not have to claim a clean house as a value. he just has to appreciate that she works hard.
My goodness I cannot even imagine the childhood she had. And it felt like Cemar is just "ho hum she spends way too much time with cleaning" without seeing that it is her way of feeling she has improved herself beyond her mother!! How is she going to feel intimate with him when he dismisses her priority and pride in a clean house with "I don't freaking CARE if the house is clean, or if the bathrooms are clean,"
But what is happiness except the simple harmony between a man and the life he leads? ~Albert Camus
