To be honest with you, I'm a bit skeptical that you can really be just friends with him. It's obvious he's much more than a friend to you. Hopefully he feels the same way and you guys can make the relationship official soon. Otherwise, I fear that you will get hurt. Good luck though.
“This planet has - or rather had - a problem, which was this: most of the people living on it were unhappy for pretty much of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movement of small green pieces of paper, which was odd because on the whole it wasn't the small green pieces of paper that were unhappy.” ― Douglas Adams, The Hitchhiker's Guide to the Galaxy
