Does this guy like me?

Ok well a few months ago during Spring Break he would text me every single day. Then after spring break was over he would text me like once on the weekends or every other weekend. Now he doesn't text me at all. During spring break he texted me saying that he really liked me. A month later or so he texted me saying that he still liked me. Now he doesn't text me at all. But I have texted him twice before and I just say a simple "hey" and then within 10 seconds or less he replies back with a simple "hi". Then we text for like 10-15 minutes and then he all of a sudden just stops texting me without a bye or gtg or something like that. It just suddenly stops. I know he is single and everything but I just don't know! Please help?!?!?!?!?!?!?!?
