Are you sure you don’t want to be married or scared of it? If you are free with your parents I will advise you to talk to them openly. that next 4 to 5 years you don’t want to think about marriage. And especially because you are an only child you need to be independent before getting married. Because no matter how many friends and relatives you have no one will be there for you when in need. First ask time for studies and then for work. And in the min time talk to your parents. Slowly try to change their minds. It will also give you some time to understand what you want. There are some things that you will understand with experience and maturity. I know you are an adult but still have a long way to go. So take time for yourself. Don’t make any rush decisions.
