so i am a freshman in high school and i have a crush on a boy who is a senior and he is really cute and he seems like a nice guy on the quiet side

at the beginning of the year when i started to like him i requested to follow him on instagram and he accepted and requested to follow me back and later on in the year i “accidentally” texted him hi but then i got scared so i texted sorry. but a few minutes later he texted hey babe but then said that was not me and i saw it and tried to text back okay with question marks but he unfollowed me so it wouldn’t go through and later i added him on snapchat and he added me back and occasionally i would send him snaps but he would only open them and i don’t know whether i should tell him i like him or not but what should i do
