There's this guy with a girlfriend who stares at me quite a bit during class and stuff, but he won't actually speak to me. He blanked me the other day, and when he was walking with one of my friends I called out to her and he was like telling her they couldn't go over. It's really upsetting because he's known as a really nice guy, and is really nice to my best friends, but apart from saying 'Hello' to him once I've never said or done anything to him. Please help.
