HOW TO ATTRACT NICE GUYS?

Ok, im a high school student and i really want a boyfriend, the problem is that i only attract those jerky jock dudes. i want to attract a nice guy in my geometry cl. he's really cute, but i have a feeling he thinks im snobby. i'm not at all snobby,but my clothes and the people i hang out with kinda say that. i wanna get away from the popularity and find a nice guy who will really care about my feelings and not my looks. what can i do?
