Anyone girlfrind help please !?

-Okay i was just wondering if this is normal i have been dating this girl for almost 5 months now we live in WV but she moved here like 2 years ago from PA and like i guess all her friends still live there but here is the question. She talks to boys on the phone for 1 hour to 2 hours a night from there is that normal? And text them a fair amount is that strange? And should i be worried ? I was just wondering thanks.
