long distance advice!?

I met a guy while traveling to Dallas for work and I recently went to spent a weekend with him and I currently live in Colorado. I've been having the worst withdrawals from sleeping alone after 4 nights with him and I'm feeling so stuck and scared to fall for someone in another state. I do travel down there a lot and get to go back in 2 weeks! Any advice to keep that spark there or how to get over the sadness any advice at all helps 💕🙈
