My fiance broke up with me....OVER THE PHONE!!!

My fiance and I have been together for 3 and a half years. Our wedding date was January 26, 2017 on our 4 years anniversary. My fiance called me at work on a private call to pack up my stuff because he is breaking up with me and hung up the phone before I can say anything. I live with him and his parents. We was in the process of putting money down on a apartment because we want to go home to our OWN home after the wedding then he tells me this bullshit.

I am so heartbroken because I really thought we was on the same page and never gave me the feeling that he want to call it quits. We just had a AWESOME date on Sunday. I don't know what to do. I am hurting so bad right now.
