Nikaah & Marriage Issues

A wifes primary duty is her husband and children

Q: I am currently taking care of my parents who live in the unit next to me in a complex. My father wants me to buy a house so that I can accommodate the two of them (parents want to buy the house for me) but they do not want my husband to stay with us (they can't get along) and don't want my married children or grandchildren to visit on a regular basis. I cannot live without my husband and children. My parents want me exclusively to take care of them.

I'm the daughter and I have 3 brothers who don't want to take care of them because of previous issues with their wives. I do not mind living the way I'm living in a rented place because I have my own space and they have their own space.

Am I suppose to be listening to my parents or does my own family (husband) take priority. What is the Islamic view? 

Child remaining in the womb of the mother for more than 9 months

Q: In Behishti zewar theres one masala that states that if a husband passes away and then after a year the lady gives birth to a child, it will be attributed to him (she didnt get married again at all after his passing). Conception happens a few days as afterwards the nutfah dies and conception is only 9 to 10 months.

Is it normal for a mother to carry an offspring for 12 months?

Girl attracted to the same gender

Q: If a girl has been behaving like a boy naturally since birth, she has a strong fear of Allah and a desire to walk according to Islam. She tried to correct herself and did everything that girls do, but it didn't make any difference and she is still attracted to girls. All of this is natural for her. She has now decided to seek medical help and undergo hormone therapy because she is not getting better despite waiting and trying. She has a strong hatred for LGBTQ. She also visited a doctor and the doctor said to them, do a harmons therapy. Please give me answer what should they do?
