Whats up with this guy i like?

ok i like him and he knows it. he stares at me, walks by me like he wants to get close to me on purpose and idk why but i have seen him drive by me when im walkin home and he lives the other way. i know he likes this one chick because his friend told me. she looks nothing like me and she more around his age group(me:freshman.him:senior)well recently i told his friend that likes me that i dont like my crush anymore. his friend seemed more than happy to give him the news. they next day my crush didnt look at me, saw me walking and drove his own way. i saw him with that girl he likes TODAY and he drove by me the way i walk like usual
