Confused.....please help

Hi I wonder could someone offer some advice on this one.
I met a great guy 2 months ago. We re both english but he lives abroad in the states... He was home for 2 weeks when we met in Ireland. We hit it off big time and we ended up spending 10 amazing days together, 24/7!! I've never connected with anyone like this before in my life and I know he felt the same.... Anyway he went home, it was very sad, we both cried etc.
Anyway he started emailing and texting when he got home, he did most of the pursuing and basically we've had a bit of a long distance thing going on for the past 6 weeks.... It's been amazing, he d text me really sweet things like how he only wants to be with me etc etc
anyway the exciting thing was I was going to be in a nearby state for a week next month for work and he was gonna come visit me!!!! We've been planning it and talking about it for the past 6 weeks..... Each day he'd text how he couldn't wait to see me.... I was living for it!!
Anyway a bomb dropped the other day when he revealed that he couldn't get time off work to come and see me..... Because of this we also decided to stop texting cos Its too hard, this was his idea...we ve also decided to just email sparingly....I tried to be very cool on the phone, I'm so scared to put myself out there for fear of getting hurt, for fear of looking desperate
I don't really know what to do
I think I was falling in love with this guy, I'm not ready to give up on us because of distance
but now I'm getting paranoid also, is it possible he was just playing me? Stringing me along the whole time?? Why would a guy go from being so into it, so intense! To cutting all contact all together?
Please comment, I'm so confused...
Should I tell him that I'm crazy about him or try to forget and move on??
