Why would he say I'm not his type anymore?

Ok, so I met this guy on Myspace about 9 months ago. We both thought each other was awesome, and then we found out that we lived about a mile apart. So We finally met, and we had a great time. So we kept hanging out after that, and then it became more. I started to love him, and he was the best boyfriend I had ever had. Well, a little bit ago, he started treating me like crap, because he says I'm not his type anymore. I don't know what I did wrong, and now we just don't talk anymore. I miss him so much and I don't know what to do about it. He is so perfect for me. Help?
