should i tell him?

Yeah, wewe should! Some chances never come again! For example, if wewe find soemthing he lieks like wewe do, start a mini conversation like with a compliment au a question. au try to get involved with the same things\groups like him. Or,(xD) just talk to him. It´s better though to be around 95 percent sure he likes wewe back before wewe tell him, it could be rlly embarrasing. Well, it depends, sometimes there isn´t rlly a plan how to do it, sometimes wewe just have to make one up as wewe go along. Well, good luck! =)

i had the same problem two months zamani but the boy i liked was in my bus and i known him from 3 years.
so, i think that wewe have to confess to him either kwa talking to him au kwa giving him a letter like i did :)
but the most important thing is : DON'T LOOSE FAITH!!
because i thought that the guy that i've confessed to him hated me but he actually liked me !!
so, yes tell him :)

talk to him more! if wewe really like him and wewe think he likes wewe give him some clues. wewe can even sometimes tell it to him straight. if he says something funny, tell him he's funny! if wewe just feel like wewe enjoy spending time with him, tell him wewe like when he's around. go for it! yolo!
