confused...........

I am not feeling too good today at all. The weather isn't so great outside also. For some reason, a lot been on my mind lately. I don't know what he is thinking. I wish I knew. I am starting to like him a lot but then again I am scared to like him more and more. I don't want to end up getting played or hurt. I already wasted a lot of my time on a useless person and I don't want to repeat this over. He treat me nice, I enjoyed every moment around him. When he is around, I am very happy and he always put this smile on my face. But the thing is, what am I to him? What is on his mind? I don't know what to think anymore. I just wish I can just ask him straight up but I am scared too. He don't seem like he like me that much. I have this only feeling that he is not into me and I am the one who like him. Should I just back off and leave the way things are or should I asked him what is going on?
