advice requested (about a girl)

ok, i’m slightly confused/reluctant to start a relationship with this girl back home. i’m currently deployed to afghanistan and she’s finishing high school back in my hometown. we’ve been friends for about 5 years now, i realize i’m probably friend zoned. i asked her out when i got leave mid-tour and she said she doesn’t date. i realize that may be true but i know she’s had boyfriends before but nothing very serious. i’m planning on trying again when i come home from deployment.

any help with this is appreciated. if you need more information let me know.
