Honestly, I say give it one last try. You don't wanna seem like a stalker, but at the same time, you just don't want to give up.

A suggestion. Try to not force a relationship of anything more than friends. What I mean is, You should make it clear you don't want her to break any rules she may think are part of the religon. Instead. You can focus on something like..."Since online relationships may cause you to sin, what if it becomes more than an online relationship."

But that only works if you are willing to move or meet her, and vice versa. You could just stay friends until that day as well.

sorry if you don't understand my suggestion that well. But yea. Don't give up without one last try!
