What do you think about this? I dont know what to make of it.......?

I been seeing this guy for about a month.When we met he acted like he was crazy about me.We live in different provinces and when i left he started to cry b/c he though we would never talk again.Well he has called me everyday since we met and we talk for hours. He brought up the idea of him moving here to be close to me and he said a couple days ago that he was 99% sure he wants to move here soon.His friends are also giving him a really hard time about moving here.We had a serious convo 3 nights ago about how the long distance isnt going to let the relationship develop properly & he agreed. He said he wants to make this work and he has some serious decisions to make, but feels bombarded. Ever since we had that conversation, hes been acting different, kinda distant. I am going to visit him in a week, so hopefully that will help him make his final decision. What do you think about all this, and why do you think his behaviour changed? I am getting worried his feeling towards me changed...?
