Boy trouble

Emily

Ok so there is this guy and he first liked me in 3rd grade and I put it off until 6th grade and we “dated” for like 3 days and we were each others valentine and then a year ago yesterday he said that he likes my best friend and I found out she liked him (btw he is the only cute guy in my class) anyway now I’m in 7th grade and we liked each other at the beginning of the year and now he is sending me mixed feelings... idk if he likes me but we both are to “shy” to talk to each other unless we are in a group and I can’t seem to not like him anymore. Any advise to get over him??
