I'm a visiting student in England that only has 3 weeks left before I go back. I want to tell a friend I like him but I don't know if I should. 

Since the first semester, I've had a small crush on him to the point that I was a bit weird/awkward around him (ugh it was like middle school). He was the funniest guy I ever met! But I never pursued it because I hated feeling awkward, was afraid of rejection and other reasons. Over the next months, I got over the crush, was normal around him and we've become quite good friends. But now the crush is back... I want to tell him that I like him but what would be the point really? I'm going to leave in a few weeks and I don't generally do flings. Plus I'm unsure about how he feels about me. Based on our texts/fb messages, my friend thinks he likes me but then again, he has a lot of friends who are girls so what do I know! 

Obviously, there's no real future here. But still should I tell him that I like him as a just so you know thing? At least it will boost his confidence? Or would it be too awkward between us if he doesn't feel the same or feels the need to do something about it? Not only do we have a few weeks left, we also plan to keep in touch in the future so I don't want it to be weird between us....

So, yes or no on telling him? If yes, how do I phrase it?
