Unsure Feeling

After a few month of, I tried to start all over. I began to pick myself up. Along the way I came around a fellow name John. He reminds me myself as his girlfriend began to treat him differently. At that point I know that the relationship was going to end, also I decide to help him out. Not because I was smarter or anything, the reason I know that relationship was over was because I had experienced it myself. Me and him became good friends, we know we had each other back. Well back to the topic, as I began to start over, I began to have conversation with this girl name Deedee. She is not the most popular girl, nor is she the hottest girl. Whatever, it doesn't really matter. Well we went the movie, we watch Avatar, and things just begin to heat up. But I told her, I am not ready to commit to a relationship. Because I am not sure about my feeling for her either. I don't know if I truly like her or am I just using her as a rebound. I have a special feeling for her, and I enjoy her company. But I don't know when will those feeling going away. I don't want to think about that when I am with her, but it just bugs me whenever I am with her or when I am talking to her. This unsure feeling is killing me.
