How can I communicate with my crush?

[me]

You should text him on kik! I was once in the same position as you and the only thing I could do was text him. When you start texting him you should be cool about it and try no to text a million messages at a time and try not to reply as soon as he sends the message. If you start talking to him he will probably start texting you regularly and maybe soon enough you could have the courage to tell him how you feel! If he is kind of popular you shouldn't tell him how you feel in person or I'm a note because this could end good but bad.
If I were you I would start texting him in kik and starting with hey it's _______. Then after you guys start talking you could ask him for his real number!
Hope this helped!!
