he just wanted to be single but i still dont understand why!?

So this guy and I dated for about 2 weeks and a half. I know it was not long enough and all but we had been talking for about a month and a half but the bad part is that when we were talking he had a girlfriend. He really wanted to break up with her so I thought it was not bad, although he had been dating her for a year. He eventually broke up with her and partially he did so because of me. He would always say the sweetest things as: "Your perfect, i'm so glad I met you, and I would be even happier if we moved on to the next step into a relationship." We went out on a date and he asked me out that night. I said yes of course and I was so happy and he seemed like it too, but when he broke up with me, I felt horrible. He broke up with me in a text message and said that he saw the relationship more like a friendship and he wanted to be single but still wanted to be friends. The first 4 days after breaking up with me he would never acknowledge me even though he had said he wanted to be friends. I never called him or texted him or questioned him about it because I wanted him to come to me. Eventually he began to be nice to me and be a little flirty. To my friends it seems like he is not taking me for real and is just messing with me but I prefer this over the fact of him not talking to me or acknowledging me. He hugs me in a way like if we were dating and he just makes me believe we could go out again but I don't know what to do and think. I'm so confused, and I would love to talk to him about it but I just don't want him to know that I still haven't gotten over the fact that he broke up with me. I came to found out that he was holding hands with his ex of one yr on the last day of school and this is what driving more than crazy right now...
