Why does he say that he likes me and I mean alot to him then he ignores me?

So I knew someone last year and he was in my gym class. I had a crush on him the whole semester, but I never told him. At the end of the year he moved away, and I haven't seen him sence. But almost two weeks ago my friend was spending the night at my house and I went on her facebook and I noticed he was on chat so I sent him a message telling him it was me. And we were talking and we both remembered eachother and we were talking bout things that we remembered about eachother and I started to like him again. I just didn't say anything bout it. Then my friend had to go so I gave him my number and told him to text me. Not even 10 seconds later I got a text from him. We texted eachother till almost 2 in the morning. Over the next week, we texted every day. We talked bout everything. I even admitted to him how I had a crush on him that whole semester and he told me that he liked me then to. Later we were playing the question game and I said "ok do you like me as more then a friend..?" and he said "ya.hbu?" and I said "yea(:" then we talked about how we still like eachother. He's told me how much I mean to him, how I'm his other half, and he said all this sweet stuff. The other night he even said "(: I'm goin to bed nighty night. Love ya!" it made me really happy. We've talked on the phone and everything and he's just so funny. But here's the thing...some moments he's telling me how I'm his girl and he says how much I mean to him and other times he'll ignore my texts for hours and when he does text me he doesnt really say much. Then he'll say how much I mean to him. Then it's right back to ignoring me. I think he really does like me alot and I believe that I do mean alot to him. It's just sometimes it confuses me, how he acts. What do you people think??
