Oh, man. This is so true about me and a friend I knew a while back... he was so sweet to me, and we always talked and laughed together, but our age difference was a couple of years, so I knew I could never date him... I still miss him. ;u;
I was in such situation few years ago. I felt in love with my dear friend. And I even told him what I feel. Feelings were not mutual, but he never made fun of me, he was still my friend. With time, that feelings have gone and now we are best friends. And I'll never forget what he has done for me.
