Did I ruin my chances of dating this guy by what I said to him?

I met this guy at school through a mutual friend whom I collaborated with on a school project. After the project was done, he asked if I'd like to go out sometime and told him yes he had my number. He texted me the day after and we chatted a bit. The next day I saw him at school and we chatted again. The following day we briefly saw each other through the hallways, but he was about to leave without saying goodbye when I asked him about it. Then he told me he'd text me later, but I didn't hear from him at all for the rest of the day. Right before that, I felt that he was losing interest. The following day, I texted him and didn't get no reply. I texted him a few more times and still nothing. Then I texted him telling him that I don't appreciate him playing games and that not to "fk" with me anymore. A few minutes later, he texts me asking what he did wrong and called me. We talked about it and I told him that he proved me wrong. He also told me that he didn't know I was interested in him but that he was in me. He told me that he'd call me later and to have a good weekend. The following day I heard nothing from him. Did this guy lose interest in me because of what I texted him or did he already lose interest even before that? Can I gain it back? He goes to my college but most of his classes are in another building. Please help me. This guy has all the qualities that I'm looking for in a steady boyfriend. Thanks!
