Shed some light on this for me?

Our relationship was going great. About a month ago he starts talking about moving away in several months. He was still very affectionate and things were good but at times he would act distant or wierd. I was starting to worry cause even though he talked about moving away he never mentioned where it left us. I was getting irritated with him for it. His last serious relationship ended because of long distance and it still bothers him. He went away on a trip and asked me if I would wait for him to come back I said yes. He called or texted me constantly the whole time he was away. So he comes back from his trip and acted like he didnt care to see me. I got upset and he says he is going through a lot right now and needs time to himself and doesnt want a relationship right now. He said he could use a good friend and didnt want to loose me. I went over to his house that nite and he held me. The next morning he held me and kissed me and told me he was sorry. We talked about it all that day and he would hug me and say sorry. I tried to sway him but he still stood by his decision and say he couldnt be with me and needs to figure himself out. I told him I could not just be his friend. I am so confused right now and I want to see and talk to him but it hurts too bad and feel I need to move on. He has called me and we have talked. I missed his call yesterday and he got mad like he always used to and is still checking up on me. I wrote him a letter saying this; yes we do need time apart but there has to be a time limit I wouldn`t wait forever. That I still wanted to be with him more than anything and try. And that I support him if he needs help like an emergency, but as I said before I don`t want to talk and I just cannot be his buddy its too painful. Its either a relationship or I have to move on. He hasnt tried contact since he got letter. I don`t know if he was letting me down easy or if he really does just want a break. And its not about a call believe me.. Help?
