Does this guy like me?

When I met and hung out with this guy, I could tell that he liked me (followed and teased me quite a bit, while being a gentleman). The only times this guy has contacted me after meeting him and before our date was when he called the Monday after we met (we met on Friday) to confirm our date and then that Wednesday, twice, to tell me he was going to be late. We went on a great first date last week and he some of what he did when he first met me, but also added showing off, looking at me, and stuff. He ended the date by giving me a big hug that was a few seconds long , telling me that he had a good time, that he would see me later and to have a good night. A few days later, he went on a vacation with his family at Laguna Beach, California (which he mentioned several times on the date that he would be going ). It was his birthday on sunday and I texted him "Happy Birthday such and such. I got a text real quick saying thanks. I also texted him, a few minutes later, "23 at Laguna Beach, you lucky bum :)" but I didn't get a reply from him. I haven't heard from the guy since our date (a week ago yesterday). Now, what I'm wanting to know.............is this guy not texting or calling me during his vacation because he's acting the way he did before we went on our first date, which was he only called to meet up with me? Do you think this guy wants space and is waiting to come back and contact me?
