<human>: Bear with me - this may sound like a crazy story. But it's totally legitimate and wonderful.

I just met this amazing guy, literally last week. We've known each other for a total of 9 days. 

We went rock climbing on our first date, then out for drinks and dinner that night and decided spontaneously to go to Las Vegas the next day. And it totally happened - we took an amazing road trip to Vegas with each other (basically still total strangers) and had an absolute blast for 2 days before road tripping back home. 
We spent the rest of the night together, then were together constantly since the day we met. Spent the night together every night, spent all day together everyday. We had an amazing time. 

The thing is, he's in the army, and based in a different state and was just here on leave. I'm 2000 miles away in a different state from him. We decided last night to make this a "real deal" relationship, we want to try this! We both mutually agree that we like each other enough to really try to keep this going. So we're already planning a visit for me to his state soon.

He plans on moving here soon, hopefully by the end of the year. So if things really work out, we aren't permanently apart.

What are some ideas you have to keep this fire burning for us in the meantime? Has anyone else been in a situation like ours? What can we do to prevent this from fading before seeing each other again?

Thank you r/relationships :) You've only ever helped me before, I trust you!

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Met a seemingly perfect guy only 9 days ago, went to Vegas for our second date, fell for each other big time in a super short time but he was only here on vacation. Long distance already.
