If you're asking
"If God why evil?" or
"How can there be a God when there is so much evil in the world and my life?", the answer is this...
Mankind is very corrupt, and around 90% of the bad stuff that happens out there is because of our selfish harming of each other and ourselves. That all boils down to free will and choice. God had nothing to do with it other than allowing so that we aren't just puppets on strings. He lets us make our own decisions even at our own expense because he values our freedom to choose. As for the other 10% of the time when evil is a freak accident or illness or natural causes (i.e. when it has nothing to do with our personal choices), this is because mankind brought suffering and death into the world with our original sin of disobedience in the garden of Eden.
Effectively speaking, evil is only and ever the fault of humanity. Not necessarily in a direct fashion,though. We aren't always being punished. We're just living in the world we've chosen. This is why innocent people die who never deserved it.
Plus, God sometimes lets us suffer evil so that we can choose to overcome it and grow stronger. After all, how do you get stronger and grow as a person without adversity and environmental stress? God has a bigger picture, and developing us while letting us make our own decisions is a big part of it. He never causes evil, but only allows it, and will remove it some day.
As for the girl, I am happy to hear that you are in love, and this is a blessed thing. I congratulate you, because I have great respect for lovers who fight for their prospect. Though, as it's been stated, you should come to Christ not for a girl, but for Christ himself because you need his help. Romantic Distance isn't your greatest issue in life. Not having a saving relationship with Jesus Christ is.
Let me make a suggestion... Talk to this girl. Ask her about her faith and have her explain it to you in detail. I make a promise/deal with you now: if she is as Christian as you say, she will not refuse to tell you, and will be more than happy to share with you all the details. Plus (*wink) this could be your chance to kill two birds with one stone and both get saved and get a girlfriend in the same blow. Not a bad deal, huh?
But seriously, I promise you, if she is as Christian and traditional as you've described, I'd bet my life twice over that you could get her into a very long, productive conversation with you over the Gospel.
Just go up to her and ask her to share her faith with you. Seriously, try it. She'd be thrilled. Also, why don't you ask her about the whole "If God why evil" thing.
In fact, just go for it and ask her out to a meal where you just ask her questions about her faith. It's a win-win situation, because you get what you want answered, and you get to go out on a date that I'm sure she won't refuse.
Blessings friend,
