I am really stuck

Um so there's this guy I like in the country I used to live in, and it actually realistically felt like he had feelings for me
​But now I'm living in another country temporarily, and I can't communicate with him because the site won't load at all. 
​I really want to tell him somehow that I like him,  but I can't now cause I can't even talk to him
​Out of all of the guys I have liked before, this guy I have liked the most and I haven't seen him in a long time and when I didn't see him, I felt I liked him even more and so basically I'm in love with him. 
​There's not much to do to help to be honest. 
​I just can't stop thinking about him each day.  
​This was the last thing we chatted before I never talked to him again
