I need to know if this guy is playing me?

I just moved to a new city and started a new job. This guy at work asked me if he could show me around town one night. I had already liked him and so of course I said yes. It ended up being a date, which I wasn't sure if it was going to, and I think we were mutually attracted to each other, he came back up to my apartment... He's really busy with class and other stuff and is only free one/two times a week. But part of me thinks he's just using me as a hook up. He never texts me or whatever. I don't know what to do, I really like him, but I'm afraid he's going to break my heart and just stop hanging out with me all together, advice?
