No one will answer, but I really need your help :(?

My boyfriend broke up with me on Friday. It is killing me. I have been broken up with before by a different guy in the past, but this time its worse, because I love him, whereas I didn't love the guy from the past. He is a coworker of mine, and yesterday he worked a shift. My best friend also works with us, and apparently he asked her if I told her what happened, and of course I did tell her. She says he was fairly quiet all shift, but he did talk to her, but whenever she would ask what his take on the breakup is, he would say that he doesn't want to drag her into it, and he wouldn't really tell her anything. I want him back so bad, but I don't even know what to do anymore. I went for lunch with my best friend yesterday at work, and the entire time I didn't acknowledge his existence (he was in the same room) he didn't try talking to me though. I laughed and talked to all the other people in the staffroom though. He hasn't called me or emailed me at all. He said when he broke up with me that he hasn't given up on me, but that he has given up on the relationship, and that he wants to remain good friends. How can I get him back though? Please give me advice. I'm dying here.
