What should I do? Are we still together or what?

I don’t know what is my status now with him..he is a funny happy go lucky person. And always surround by his cool best friends. He kinda careless bout feelings.. All he knows is happy happy happy… And I’m the sensitive one..emo.. I always take things seriously..compared to him..he take it easily. I can say he knows bout me lot..because I’m always seeking him..talk to him if I got probleme.. About everythings of myself.. But… I only know bout him is he is happy2 person..luv hang out with his friends.. I tried to know him..but he didn’t allow~.. Sometimes I can feel that he got problemes..or some thought about me.. But when I asked, he just keep denying..and being happy . Sometimes I see my attitude to see his reaction.. But he just keep silent..what I wanted is that he can express his emotion that time…about me..bout what I’m doing..so I can know what is exactly on his mind. But nowadays, I hard to believe him because he keeps denying bout what is exactly his feeling to me. I mean..its ok if he mad at me..hates of what I’m doing..just let me know. And he just said he is ok with all things that I do..(even hurting him..) all the time is ok??
Then..we just got arguing. And he keep away from me..phone, myspace, ym… (he already delete his photo in ym; which is from my editing)..I was so hurt..& deleted him from myspace..then he set his profile to private so I can’t view)…and he said he had enough for me.. Act so many things happened in our relationship..kinda complicated to explain here..
