Fear of getting married

Q: I am scared to get married but my parents are forcing me. I grew up in an environment where my parents fight everyday and both of my parents are involved in extra marital affairs. It is upsetting for me because obviously nobody will accept that and suppose, even if I do get married and that person gets to know about it he might leave me... Please help me as I am getting rude towards my parents. I am trying to keep myself close to Allah Ta'ala but as soon as my parents are telling me anything related to that I am unable to hear it.

Wife cooking for her in-laws

Q: My married son and his wife says that there is no duty of the daughter in law to make food for the father in law, mother in law and brother/sister in laws. Even it is not her duty to make food for her husband, rather it is the duty of the husband to provide food for his wife and they claim that this is the law of shariah. My question is, do they get married only to fulfill their sexual needs and bear children? What does shariah say in this regard?
