I ve noticed a guy at my university who has always been staring at me since the last couple of weeks. I don't know since when exactly because I never really noticed him that much since I was going through some issues but in the last 1 month, I got a bit curious about him since i also found him attractive.
Twice, my friend pointed out that this guy was staring at me. He smokes outside so each time I went outside, we would have eye contact and he would keep looking at me until I looked away or went away.
Once he was alone, scanning a book on the scanning machine, and the moment we saw each other, he kept looking at me. I was also looking back, about to go up to him until a girl I know came and I went to chat with her.
Yesterday, I was talking to the same friend outside and she nudged me towards him. I caught him watching me again.
Today, similar thing happened. I wear some pin badges on my lanyard which I was fixing when I went outside on campus. He was outside, smoking again and my friend and I saw him watching me.
While going home, I crossed paths at him and he made eye contact with me again before going out.
He is a quiet person and mostly keeps to himself on campus. His interactions with others are very brief, short and limited.
Why does he simply stare at me? I want to chat with him but don't know if I should approach him or not?
What do I do?
