Dating for six month, what now?

Ok this is a very long story but now its really driving me crazy and I desperately need some good advice.
I am 19 years old and the guy concerning is 22. Last summer I met him in Lloret de Mar (Spain) which (I know) is not the right place to meet a men. And he also tried to sleep with me there. But I don’t do one night stands so we didn’t. So we talked which was great. And after that holiday we stayed in touch and started dating. After our first date I found out that he had just broken up with his ex girlfriend he dated for almost 3 years right before that holiday. So I said that it was better to break things off so he can have some time for himself. And that I am too good to be his rebound. And he convinced me he was over her. Things died already before he broke up with her.
After this he suggested I’d come over when his parents weren’t home and I could stay over. What also made me mad. And we argued about that too. And we fought about more things like this. Also that after 3 months he was still ok with me seeing other people.
Next to all of this he is a very sweet guy. I have a lot of issues with my family and he is always there to talk to me about this. He listens gives advice. We talk everyday and usually he initiates this. We text every day, all day actually. And there is no drama anymore.
But now we are 6 moths further and we are still not officially a couple and he doesn’t want this. And I don’t understand were this is going. I don’t think after 6 months you can still say we’ll see were this is going.
There are also something don’t like e.g. he never comes of with a creative date. Sometimes we go out have a drink of we go playing pool. But he rather just goes home and watches a movie. Last week we had sex for the first time. But I don’t know what to do now. He’s driving me crazy. I tried everything during this 6 months dated other guys but this didn’t work cause they fell in love with me or I stopped it cause I liked this guy. Can you give me some advice what to do? Cause I am lost, and no one I know can give me good advice either.
Love
