Allowing one's wife to visit her parents who have bad habits

Q: Somewhere I read that a husband should allow his wife to visit her parents home weekly, but what if her parents teach her things which affects me and my family (husband's family) like they teach her not to do work in the husband's home etc. To avoid such problems, I don't want her to go to her mother's home.

My mother in law and father in law usually fight with each other, sometimes they also hit each other and exchange very bad words and scold that's why I usually tell her that I will also accompany her whenever she goes to her mother's house and tell her that I won't leave you there alone. By this she sometimes feels bad and behaves differently. I told my mother and father in law as you people fight I'm afraid to leave my wife in your home, and suggested to them to read fazail e Amal daily for their improvement. Please advise me what to do.

Fantasizing about a man

Q: If a unmarried girl imagines having intercource with her future husband, is she sinful? She is not engaged yet. She doesn't imagine any face of a man and doesn't imagine any private part of a man. She just think that she will wear a western dress and present herself to her husband. And she imagine her husband will play with her private parts. She does not touch her private parts during imagination. She just fell on the bed and started imagining that she is with her future husband. Does this count as masturbation? She does this practice once a day. She reaches her climax point during the imagination. Is she doing a haraam? Her parents are trying to get her married but not success yet.

Informing one's parents about one's fiancees past

Q: My father introduced me to a potential spouse. We talked on the phone and through texting got to know each other better. We feel we are very compatible. He mentioned to me in his talks that he had been married about 9 years ago. He was 23 and she was 56 years old. Now he is 32 and she is 65 years old. The marriage lasted for about 2 years. He told me the reasons for the marriage and why it ended. He showed me all his documents and assured me that I could ask all the questions and that they would be answered. He is of good character and he has wants to become a hafiz In Sha Allah. He has memorized the 30th juz and surahs such as Surah Mulk, Surah Yaseen, etc. He has told me only about him being divorced as in our culture a Muslim divorced person is viewed as such a taboo. He had sure that I be aware of his divorce as I would be the one becoming his spouse. Is it necessary for him to tell my parents before getting the married to me, knowing that they will reject him based on being a divorced person?
