Is he coming back?

I had a really good relationship w/ a guy this summer, but after our first kiss, he just kindof ignored me. I was really distressed at first but feel a lot better about it now, but now he is starting to sit by me so he can talk to me in cl. He laughs at all my little jokes and talks to me on a pretty personal level. He is even starting to walk with me in the hallways again like he did at the first part of the year (before our kiss) DOES THIS MEAN HE'S INTERESTED IN ME AGAIN? or is he just wanting to be friends? I don't know what to do b/c I do still like him, but I don't want to wind up getting hurt by trying to rekindle our romance. What do you think?
