It's always hard to ask others about Love. Go for it. Do everything possible behind her parents' backs. Pressure her, at first, then back off. Unless the pressure is well-received. You didn't speak of problems with your relationship with her, I guess, it's her parents. Is she obligated to go knocking on doors for the Word of God? I don't care, it doesn't make any difference as long as she's into you. If she is, be with her as much as possible, until she gets out from under her parents reigns. I know it's your only choice. Or just go for another option for the time being. At this point in the message, I was diverted for 10 minutes, all of which were spent at a boiling point because of my girlfriend, so I can only say one thing. Choose your lover, wisely.
