How do I know how he feels about me?

Ok, since the beginning of seventh grade, I have had strong feelings for my best friend. He is the perfect guy for me, and he is like a brother to me. He is perfect, and would be the perfect boyfriend. All my friends say we would be a perfect couple, and we are destined for eachother. We flirt all of the time, and we hang out all the time together at school. He always looks at me with his big brown and hazel eyes, like he feels the same way. He has been my best friend since day 1. About six or seven of my friends say he likes me, and he said he really likes my personality, he told me. Only two people know I am in total love with him and I want to keep it that way. I have dreams about him all of the time. Three days ago i had a dream about him where he kissed me and said he loved me and since then i havent been able to get him off of my mind, and i have missed him all summer and i love him, and i really want him to know how i feel, im scared to tell him because what if he dosent feel the same way? i would be crushed. so somebody please help me, i love him so much and i dont want to lose him. :/
