Okay, so there's this guy....?

There's this guy, I like him, a lot. I had I.S.S. with him on Monday, Tuesday,and Wednesday. Monday, we flirted all I.S.S... Tuesday, we did the same. But on Tuesday he told me that he liked me a lot and he asked for my number. I gave it to him. Tuesday, in I.S.S., He was eating a pop tart, so he got O.S.S. for Wednesday. I texted him when I got home, he was telling me how his day sucked and he missed me. He didn't come to school Thursday. I texted him Thursday, he told me to call him, we stayed on the phone until 2 in the morning. 7 hours of talking on the phone. He said that he really like me now. Friday morning, I see he, he ignored me. He ignored me all Friday. I asked his previous girlfriends if he would do this to them, and they both said yes. I don't wnat a relationship like that though, he texted me when I got on they bus. He said "hey babyy" I don't know what to do, or say...
