Best friend relationship advice

Hey! 20M here who recently confessed to 20F best friend of 9 years.

Just for context we've known eachover for 9y and have always talked everyday, about everything. For a long time now she went to live overseas, and despite that we maintained the same relationship dynamic.

Recently she came to visit me and I made my first move ever and asked her if she had ever imagined us together as more then friends, she got shocked and said no.

Has anyone gone through something similar? And do you think i should stop pursuing her forever? I genuinly belive that we have this rly special and strong bond, that could in the right conditions flourish into something romantic wise. If anyone has a similar experience what was the final outcome? Its been only 3 weeks since I confessed.
