How do I deal with "talking" to a guy that barely has time for me, but is doing what God wants him to do?

I started "talking"/dating this guy about a week ago, but as soon as we established that we like each other he started getting super busy serving his church and doing things for his praise band. He has a really busy summer, and then leaves for college about six hours away. He used to want to hang out with me and text me all the time and now it's diminishing. I'm freaking out about getting to know him because it just seems like we'll never have time to even be in a relationship. I know that this whole thing is from God, but I feel like this relationship is ending before it even starts. How can I stop freaking out about this relationship and let God handle this and see what he wants me to do with my life instead of freaking out about my relationship with this guy? I've been praying for a guy like him to come into my life and now that he's here I feel like he's being taken away. Help?
