my home

In Sudan a girl or boy remain  with their  parents until he gets a wife or she is married. And, after marriage, they have two options either to live with his wife in a separate house or live with his family. The girl never  lives alone even if she is without a husband, she is still with her father when he dies.  In this case she lives with her brother . No man will leave his  family home  and live in a separate house . Always the girl serves her brother.  When she is married the girl leaves her family to go home with her husband .

Notes: I have done simple changes to your post. I believe that I understand what you have written.

Here is a complete rewrite to give you alternative ideas of how to express these ideas.

In Sudan, unmarried people live with their parents until marriage. After marriage, the newly weds can either live separately or with husbands family. Unmarried women  never live alone. If a woman never marries, she remains in her fathers home until his death, then she lives with a brother. Unmarried men do not live away from their family. Women either serve their brothers or leave their family home to establish a new home with their husbands.

Note: In Australia, we have a wide range of options. Currently a lot of young people live at home with their parents because housing is so expensive. However many young people of either sex do live independent lives. Australian families tend to be nuclear families of husband and wife with their children, it is very rare to have other relatives in the one household.
