What should I tell my parents?

After a few months of flirting, things with my guy friend and I are getting serious. Now, I'm moving almost 12 hours away to Minnesota from Ohio and that conviently puts me a great deal closer to him (he lives in North Dakota.) I also have a lot of friends in the city I'm moving to, in addition to the job I got (the reason I moved.) The issue I'm having is that I really want to tell my parents about this guy, but I'm worried they're going to think that I'm moving just for him, since they don't want me to leave to begin with. Should I just go ahead and tell them or just leave the situation alone? Help!
