Immaturity at an all time high!

So me and this guy I've been talking to since August just got into it. So I was drunk as everrrr, like sloppy drunk in front of his apartment! So my friends called my guy to come get me. They said he was hesitant to come get me. So he finally came and got me. I woke up in his bed the next morning. He didn't say anything to me the whole time I was there. So I put on my clothes and left! I texted him later in the day and told him "damn, I can't get an are you okay" he said my head was fried lol. He asked me did I enjoy my night because I ended up in his apartment again. Mind you I was hangin out with my 3 girl friends and some guys that live in his apartment. I always hang out with guys so I don't see the problem. My thing is he didn't ask was I okay the next morning. If I saw that he was drunk and was hanging out with some girls I didn't know, I would make sure he's okay then ask him who those girls were. I told him those guys were just friends I hung with before. He told me he don't wanna talk about it and I can do what I want cus I'm grown. He was being real childish. I remember one time I caught him walking off to his apartment with a girl. I asked him about it and he said she was his homie, so I just took his word for it. Why can't he just believe me? I believed him. He claim he wanna "grow" and be with me but he can't even talk out a problem with me. He can't even communicate. We haven't talked since the incident which was yesterday.
