I can't slow down. Help??

Dating an honest guy 3 months (1-2x a month). We are 2 hours apart. He was debating moving closer to his kids (near where I live) or moving back to his hometown. He recently communicated that he is making plans to move 1k miles away from here in a month back to his hometown, returning 1-2x a month to see his kids and I and he has a job opportunity that came through there. His intention is a more exciting career opportunity, less loneliness (hometown family and friends).

Both still interested in dating each other. Neither of us is exclusive or had sex (too early). We have a great connection that is growing. Recently, shortly before learning of his move, I've been growing more fonder of him at a slightly greater intensity than he is of me. I'm having a hard time coming to terms with the consequence of his moving so early in meeting me; possibly losing what might be something great.

Is it too early to express my interest that I'd be happier if he reconsider his initial idea of moving closer to his kids and I? Also, I wonder if this change will make it worthwhile to continue the pursuit of happiness in our budding relationship?
