I understand that getting married at the age of 18 can be the basis of many problems, especially when your education is incomplete and you're still not very adept at understanding the principles and circumstances of life.
I saw people getting married or having children at that age and most of them still rely on their parents for their needs which is just sad because instead of helping their parents, they added more problems to them.
You are saying right. They often become a burden on their parents. They rely on their parents for their small and big wishes and children's necessities, and as a result, they live their lives according to their parents' wishes.
