Nikaah & Marriage Issues

Q: Is my husband a mahram to my grandmother or should she make parda from him?

Q: With consent from my parents and siblings, and my husbands entire family (but not his father), I had my Nikkah in November last year. As soon as we announced to my father in law, he was over the moon and incredibly happy. Some realtives also knew about the nikaah beforehand as they arranged our marriage. The Nikaah was beautifully done at the mosque in front of witnesses and my mother and sister. After the Nikaah my parents announced it to other relatives and friends. I and my family received a lot of backlash.

My question is, Islamically did we do any wrong in keeping the nikaah discreet from noise and simplifying it as best as we could? I have received love from my in-laws and family members who were generally happy. Some relatives and family members may forever hold a grudge of some sort. For my own contentment, I wanted to ask if I did anything wrong or were there any mistakes in hiding it from certain family members?

Q: When my son has his own job and he is earning then is he dependent on his father?

Q: I really love my cousin and he love me too. We did everything together and I regret that but it’s happened now. He told his mother that he wants to get married to me. But his 2nd mother told him that she gave me milk and to him also. My mother never told me that even my father don’t know about this. Now we really love each other and we can’t leave each other. What to do?

Q: I touched my mom with libido. Now I am deeply sorrowful for the sin. Please guide me.

Q: A father said that he will admit their child in a madrasah, but the mother said that she will not admit their child in a madrasah. The mother respects Allah and Islam, she also wants the child to know about Islam and she wants to teach the child about Islam by an Islamic teacher. The father and mother then admitted their child in a school (not an Islamic school and not a madrasah) and appointed an Islamic teacher to teach their child how to pray salaah, read Quran, duas, Islamic characters, lifestyle, etc. so that child learns about islam. Is there any sin?

Q: If a woman is on birth control, is she allowed to stop taking them without the consent of her husband? She would love more kids but he says no. 

Q: I am a boy. My age is 29. I want to having physical relations with a boy with his permission. Is it permissible?
