kiss my best friend

Well, we “dated” when we were in first grade until the end of forth grade when he had to move. We were even “married” we had little fake plastic rings. Then i saw him off and on for about a year. Then i didn’t see him until we went to the same junior high. I thought that i didnt have feelings for him anymore, until i saw him. Then he moved after junior high and i didnt see him for two years at all. Then all of a sudden he came over to my house. We are now still Best friends. We stay at eachothers houses and hang out. A few times we have slept in the same bed and used eachothers legs as pillows. And he stroked my head and played with my hair until i fell asleep. So i dont really know… I can’t exactly tell him how i feel. It could mess everything up between us.
