I need a song that fits this couple:?

this is a long distance relationship, a 14 hr drive. he's a country guy, she's a northerner that's not really crazy about country music yet. His favorite is Toby Keith. She's a nurse who's a romantic at heart, and they seem to be physically in pain when apart. They both have kids from other marriages, so totally uprooting them to move to another state could be hard. any ideas?
