Weird prob...10 points best answer...boy prob?

My guy friend is really nice. He always Ims me if I don't first. He told me he likes this girl named Nina and even wanted me to make a chain letter to people in my school saying he likes her. A lot of my friends think he likes me. At first he's like "It's really, truley good your friends think I like you." Now he's like "Now it's bad peple think I like you." I asked him about his obnoxious behavior and he said he'll tell me something on the last day of school. What do you think he'll say? What I don't get is that he likes Nina, not me and I know Nina! And whenever him and Sarah are on, he IMs me, not her. What do you think he'll say?
