I'm 20... have never had a wide range of friends but the ones i have had, have been close. Also, I have never yet had a boyfriend. It's not weird or wrong to feel that way. some people just can't handle a wide range of friends... and the bickering and gossiping that goes with it. If you want to expand your social circle, maybe try joining a club you find interesting at school, or maybe just approach a few people and try to make friends with them...
