I am lost

My man and I haven't talked in 2 days(from talking all day everyday)...there have been some underlying things bothering me that I don't know how to talk to him about it. He is going to be gone for the holidays, which I told him a few weeks ago I didn't like and I wasn't happy about it and that I am going to get more upset as that time gets closer. The holidays are important to me and he doesn't seem to care that I am upset about it. He doesn't seem to care that he is hurting me. I know it is all unintentional but that doesn't change how I feel about it...I know my feelings will pass but not till after the holidays are over, so I don't know what to do. The last 2 days have been miserable without him, I feel like a piece of me is missing, but I also can't handle the depression anymore.
