Thanks for reaching out to YourDOST. From the information that you provided, I would like you to focus on some points and explore it a bit more:
Reason for not being ready for marriage
Even anytime sooner if you want to get married, what are the qualities you are looking for in your life partner?
These two questions are a must before taking a step towards sending the friend request or talking to the girl through your parents. When you have answered the questions, the next thing you can do is to check the girl's profile for suitability and then initiate a conversation.
You must have clarity in your thoughts so that the next steps comes easily to you.
I hope you get all the strength needed to reach where you want to be.All the best
