friends with benefits? Options

[xposure]

ok so i like this guy and i asked him if were friends and he said no, we're more than friends then he added 'friends with benefits' i didnt know what it ment when he said it so i was like huh? he just ignored me. i havent talked to him in person for 2 days now. im still confused about what 'friends with benefits' mean. i dont even know why he said it because i thought he liked my best friend. since they hang out alot like at the mall and even at each others house. i havent even went to his house before. he told me that he liked me like 4 days ago (he already knows i like him cuz i told him) if he likes me then why does he ignore me and talk/ hang out with my best friend? i even asked him if he liked her but he said no. formal is coming soon and my friend said he was gonna ask me (he sorta told me himself when i was trying to guess who liked me, he told me someone liked me so i was trying to find out who) im still confused about friends with benefits, what does it mean, what is he trying to tell me?

Save yourself the trouble...and drop that idiot....friends with benfits always ends up ugly...it's not worth losing a friend over....sex, kissing, attention... etc etc...trust me i've lost many good friends that way...
