how do I convince school teacher girl to drive around 1h 1/2 maybe 2hrs to come visit?
say "you should come visit me this weekend"
This.
OR
A subtle guilt trip about you having done the same for her before. (if you have) wording is key here, don't be a dick, but hint at it
OR
you should be awesome enough that she begging to make that drive
OR
I don't know the backstory, but if this is fresh, keep driving to her to fill her up with all of your greatness and show how awesome and amazing you are. Make her miss you. She will make the drive then.
OR
If this has been going on for a time and she is not willing to make the drive, the failure is yours, or she is not worth fussing about. Move on.
