Why would a guy stop talking to me?

after he said he liked me? So there was this guy, we haven't talked for probably 2 weeks or so.we used to work together & it was awesome. He was this really cool, laid back guy & from when I started working he seemed to be making an effort to talk to me. Soo we hung out, talked on aim, then started talking on the phone EVERY NIGHT & during breaks & for anything. He would bring me home every night. Then we kissed & from there it was like we were dating, but without the title=/then the same day I got transferred to another store, things got weird. Soo long story short, he stands me up on a tuesday but calls that night to apologize & explain how he didn't want to get too close but he didn't like me & wanted to keep talking, but he basically stopped talking to me after that. Its so hard because I got so used to him, but I don't understand why he'd call to apologize, still say he likes me & then completely ignore me all together. I don't get it=/ I miss him, but now his ex keeps bothering me to stay away from him & supposedly he's saying stuff about me, which I don't believe because he wasn't a horrible person, but dam. I'm just so confused. Why would he?
