Ill treatment from one's father

I need guidance that how I should react when my father hurts me and my mother with his rude words. No doubt he has brought me up, gave me education but nver showed affection to me. I am the only child of my parents but he has never pampered me. I only got love from my mother. Now I am 29 years old women unmarried but engaged. My father has a greed for money. My mother is a patient of multiple problems but he never cares for her, rather makes her feel like she is not so good. My mother is a very kind person but my father never appreciates her nor me. Neither he offers prayers. Now my question is when my father crosses limits fights with me, I control my anger but sometimes I say back to him but logically how should I react with him? When he don't talk to me how I should greet him when he don't see towards me because I fear Allah. Please guide me and ease my pain.
