LOVE..? this is infatuation. You guys hang out yes, but that doesn't mean anything. How long have you guys been hanging out? Just because you do alot and know many things about her doesn't mean you love her. you always want what you cant have. she is probably one of those girls who is REAL and just an awesome person..those kinda girls everyone likes and wish they had. go for it...ask her out sometime because if you don't.. your freind will...yes that may be harsh towards him but ur an adult(atleast i think u are) and u just have to go for it. if u were to go for his ex girl or someone he's liked for years and years it may be harsh, but this is a different situation.
