I can’t get over a guy who might not like me. I’ve known him for three years, since when I was 15. Throughout high school, we talked since we had the same classes, but no one knew anything about him after school.

He’s a very quiet and polite guy. However, I am three weeks short of graduating, and I’ve realized how much I like him. I can’t get over this crush. It completely overwhelms me, and I’m scared that I might have become obsessive.

We barely talked this year because we have no classes together, but I am confused if he still likes me. At prom, I saw him dancing with another girl. He took selfies with her. But when he saw me, his eyes got really big, and we danced a bit. However, every time I see him, he just stares and walks away.

Does he like the other girl? I have never had a serious crush like this before. It’s why I don’t want the year to end, because I will lose contact with him forever. I can’t just out of the blue ask him out, because we barely talked this year. This is frustrating me so much.
