If your father loves you very much, but abuses your mother, degrades her, has emotionally broken her, told the world he doesn't give a shit about her,

Is a barrier to buying cupboards and then complains about the mess, never gave her space, told her she's the servant, laughed at her and always told her she's stupid, completely broken her, been a doctor and still not given her proper medicine nor taken her to the doctor, and she is living in pain....what would your behaviour be towards your father?
