I was hurt so I decided to ignore the source of the pain completely. Then he talked to me and I was mean. Help

I have a friend. Let's call him Dan. Anyways, Dan and I were fairly decent friends. I don't really have that many good friends. I guess I have somewhat of a trust issue. I don't let that many people too close. I know tons of people, but I wouldn't consider a bunch of them to be my good friend. I really trully considered him a good friend. Back to the story. He got a new girlfriend and we stopped talking as much, which is totally understandable. New girlfriend...heck, he needs to spend more time talking to her then me. I wasn't upset or jealous in the least, I was fine with just talking to him ocassionally. Actually, it was easier then talking every day. But then I found out that he was moving across the country and hadn't told me. So my feelings were really hurt. I mean, it's not like we hang out all of the time or anything. It was just the fact that he didn't feel inclined to tell me. So I ignored him for a week or so. Then the other day he started talking to me over AIM.
