Do what you want. If you like the girl maybe calling and setting up a date would be a good idea. A guy who does nothing but text and not set up a date is just a guy who is bored and needy for attention.
Are you the same guy chasing a girl living in another country ? If yes, let her go, she doesn’t seem interested.
She’s replying on and off because you’re not her priority : you’re living in another country ! You’re wasting your time and missing opportunities near you. A virtual relationship is not a relationship. How old are you?
