well your quite young so this is tricky and it can be hard to tell, but if you really want to know ask him what he thinks of you as a person? if he says your a good friend then you know where you stand and where to go from there good luck x
give him a note saying do you like me with two squares one for yes one for no if he says no than thats fine there are tons of fish in the sea if he acts awkward than say it was a rumor that you over heard at lunch
