If you were me, what would you do?

I like one of my best friends, Elliot, but he likes my friend Alice. Jess likes elliot too and everyone thinks they are getting together, but of course he likes alice. Alice doesn't see him in that kind of way... and she knows i like him. but when we went camping they were inseprable (not her fault he was looking after her) he has not idea i like him. and i'm not sure if i should tell him. any advice? Just ask for extra details
