He's not backing up his words today. How do I get through the fear of failure?

The guy I've been involved with lives in another state. We saw each other last week and he is super in to me. I asked him what his intentions were and he said to see me as much as possible and that he feels a possibility between us. He will be living closer to me at the end of the year, so the long distance is only temporary, though we haven't gotten to the point of discussing if he would move here for me. He said we need to figure out the where and when of our next visit, and he promises to see me soon! So I said yes, tell me what your schedule looks like and what/where he prefers and we will figure it out. He said last night he would writ eme more when he gets home, but so far he has not set a date or said anything tangible about where and when. I know he likes me a lot, but I suddenly got that feeling of, what if he's stalling? Is he not really into this? I know it's too soon to sense trouble, but what do I do if he pulls away? I don't want to get anxious like this, but I have a weird feeling. Would he tell me he's really into me all the time and then not follow through? I guess I'm getting scared. Any thoughts?
