The first thing is how old are you? I am in middle school talk to him over Skype,Texting and such. See what he feels about you. Maybe if you give "signs that you like him maybe he will tell you he likes you(:
Just go up to him privately and tell him! If he says he likes you back, great! If he doesn't like you back, just act like it's no big deal. If you don't make it a big deal, then other people won't, either, so don't worry about getting teased. Good luck! ~~~MaRiA_bAbY_lOvE~~~
Salutations! For I have just recently made your keen acquaintance, and this is surely unreasonable, yet herein lies the details of my humble abode; thus you can commune with me some yon noonday, perchance?
