Guy friend problems HELP!..?

So last December everything changed between me and my really good guy friend Joe. So i met Joe Dec 2006 through a bible study i was going to and we became closer in March of 2007, and we just got closer from then on. We would hang out a lot alone and in groups and would call each other a lot. I kinda could sense he might like me..and i really liked him but i wasn't going to say anything to him because I'm just old fashion that way where the guy is sup to make the first move or something. So one night there was all this crap going on w/ him and he really wanted to talk to me about girl problems. So we were talking about it and he was really stressed out about why this girl was causing all this drama and he said "man..Caryn wouldn't it be great if we were together"..and i said "well..ya... you are the closest i have ever been w/ a guy before and i can talk to you about anything"..and he said "i feel the same way". And we were both like..."what just happened"...and then he started to tell me he liked me since he met me and what he like about me, and i responded w/ the same. We talked until almost 4am. And we agreed to be boyfriend and girlfriend. So it was Dec 22nd the next day and i went to work the happiest i have ever been in my life! And i called him on my break to see how he was doing and to see if we were still on for getting together later tonight after i get off. And he said "ya of course we are getting together..but i need to talk to you about something". And i was like "is it good or bad" and he said "bad"..and said "umm Joe since it's bad just tell me now because i can't wait 4 hours until i get off work tell me!"..and he broke up w/ me! i was soooo mad and just like what the heck man! and he told me it was a bad time to be in a relationship. And i was still mad because why didn't fig that out before last night when everything happened! and so we just kind of avoided each other for about two weeks.. but i really missed him as a friend and wanted to mend it. And on new years eve the bible study got together and he came and we barely said anything to each other. And then later that night my brother talked w/ him and said whenever your ready call my sister because she wants to talk to you. So a couple days later he called me and we worked things out and we were friends again. And we were still kinda awkward around each other in person but we talked on the phone a lot for about three weeks and then all of a sudden he just stopped calling me and every time i called him or texted him he never responded and he avoided me at bible study and treated me like a weirdo..and i just didn't know what was going on...and it has been like this for over 6 weeks now and i don't know what to do! I don't want to call him or keep bugging him i want him to come to me! But i want to know whats going on! i am soooo confused why he is acting this way! Everything was fine! what happened??? Please if anyone has any advice about this please HELP me!!! I miss my best friend:(
