When All Else Falls What Do You Do..?

So this kid he is a little younger then me... okay a ayear, but aways he liked me but i was liking another kid at the time. This younger kid found out and got mad, well he said he was not mad but I knew he was, because he liked me a lot. so now we started to talk about about a week ago and i get the feeling that he is only talking to me because he wants to do, what i did to him, to me. so now i am freaking out every time i talk to him because i get that feeling, and also, the wrost part, i am starting to like him as well.... :/
