We've kissed a couple of times but now he's distant?

I met this guy in November 2012 through a club that we are both part of. We spoke occasionally at the club and had a few laughs together. I thought he was a nice guy, attractive as well, but never really thought anything more of it. Then on a night out a couple of weeks after meeting him, we ended up kissing. We were both a little tipsy and things got a little hands on, I told him I wouldn’t go home with him and he replied with things like ‘It’s okay, I can wait for you’, ‘I want you’ and ‘you’re so hot’. And so we both went our separate ways at the end of the night.
The next day, we spoke over facebook for a bit and then he ended up getting my number (have no idea how) and we carried on the conversation over text. He didn’t reply for hours sometimes even days on end, so I thought he wasn’t interested. We spoke a little over Christmas, just general chat stemming from me wishing him a happy birthday. Then he stopped texting me.
Then a couple of days ago, we met again on a night out and the same thing happened only things got a little bit more heated. He took my number again (he got a new phone and lost his contacts) and said that he’d text me the next day. Admittedly, I do like him quite a bit but I’m left wondering whether I was just a drunken ‘conquest’ or whether he actually is interested. I’m yet to get a text off of him. It’s making me feel pretty crap and I don’t know if I should contact him first or forget about him. This is only a brief summary of the story, I kept it short because I could rabbit on for ages. Any help would be appreciated :) Thank you!
