There is a guy at school who makes eye contacts with me several times at lunch. But I don't even know him and I don't have any classes with him. I think he likes me though because whenever I meet him in hallways or on my way home, he always blocks my ways and starts asking stupid question, like where do I live, what language I speak, and if I have a boyfriend. He won't leave me alone and one time he even said that he wanted me to be his girlfriend. But I don't know if he's being serious when he says that. Since I don't know him that much, I don't know what to do. But he keeps appearing around me and he seems to be waiting for me afterschool at the places where I always pass by. I don't know what to decide and I have no clue if he's really into me or being serious with me or just playing around. Any help or advice please?
