Denny Hamlin's girlfriend Kristin Buntain,
I never imagined moving away from home. Never. But I did. I left my job I loved. I left my family. But the alternative would be to stay here and not be with him every day. After that long a period of time being together, I knew I was going to go. I haven't regretted it.
