What should I do? I don't want her to cry again?

You should try talking with her Dad, maybe it could help, telling him you love his daughter, and would do anything for her, and maybe, if you're willing, go to their Church once in a while. i Had the EXACT same problem, with a guy that lives FIVE frickin hours away from me. He's my best friend's cousin, and has decided to go with a different girl. Hope that helps!!!!!!!
