I am confused with this girl

I have never talked to her but have hangedout with her group 1 time. That time i think i herd she asked her friend who i was and i felt her looking at me until i left the place. Now 2-3 months later when i arrive to a event i see her glancing at me multiple times, she did the same when i was leaving the event aswell. It was at somewhat a distance so i couldnt see if she was smilling or not? I also walked past her when she was sitting in the caffeteria and i think i could see her looking at me when i walked past. The next day she sat herself on the tabel infront of my tabel in the cafeteria so she had a direct veiw of me and i could see her. I have also tried to add her on social media but she hasent accepted it and she is active on it, requested 3-4 days ago

Sounds like she is curious about you. She has noticed you. You have noticed her. You are curious about her. So, relax and be her friend. Say, hi Learn about her Let her get to know you. Its as simple as that. Be friends. Don't look for a relationship. Look for friendships and in time one of them could GROW into a relationship if not sooner in life, later in life. You could have a friend forever. Doesn't that sound wonderful?
