Need some advice, pretty disturbing don't read I'f you don't want to be sad

Well, I dated a girl for three years, and I'm only 18, so I consider it a long time. We had many ups and downs and loved eachother as much as the next couple, and I still love her now. She moved to another city for school, even after she told me she would stay If I didn't join the airforce, so that we wouldn't be seperated, but when the time came she still left, and I had given up my dream, at least for the time being. We lasted about three weeks, she didn't call me once after she moved, I tried my hardest to keep in contact with her. My entire store of memories from highschool all include her, or so it seems, since for as long as I can remember she has always been there. Its been two months since she left me, and we've been talking again recently, thinking about getting back together, and I really do miss her, she somehow ends up in all of my dreams, most of the areas in the city spark memories us, I had always loved her, even when we were just friends, I was the good friend who secretly loved her, that was the situation. A couple nights ago she told me that she was very drunk and left a party on her own, and while she was walking home...she was raped by an unknown man. The police came and all the did was tell them to go somewhere else, they didn't do anything about the wasted minor being raped infront of them not even able to form audible words. She is the love of my life, and I'm scarred terribly now, and I think I'm slowly falling into depression. How should I deal with this, what's the proper way to react? I never wanted her to move, so I could always protect her and keep her safe, but her selfish parents said staying home was not an option, and sent her away. They tried to break us up by making her leave every weekend of the summer, our last two months living in the same city, not caring how hurt we would both become as a result. This is what happened and I can't help but feel contempt towards them. Am I being immature? What should I do? When I think about her I feel so sad, I just want to make her smile and forget that terrible happening ever occured. She is so lonely, despite what she tells me, I know her better than anyone and I can tell. She doesn't want to tell her parents and has only told me. I've worked so hard to be on speaking terms with her again, hoping she might love me again. But I feel that her parents need to know, that something needs to be done. I also know that I'f I tell anyone, even her parents, she will hate me and never want to talk to me, because she told me so. I know she is serious. But I'm willing to let her hate me and never speak to me again, if it means helping her, am I just being inconsiderate, or is my train of thought justified? Any advice would help me greatly!!

It's not disturbing. I mean it's probably disturbing to you because it IS your girlfriend lol. But anyways i wouldn't do anything esp if your girlfriend (or EX) said don't. Getting involved and saying things to others won't help. I have a feeling nothing will come out of it except her being mad. If she's not making any efforts then you shouldn't be sweating her. i know easier said then done but you gotta wonder why she would move and not call or speak to you for that long. Obviously she wasen't as invested as you were. I hope things work out for you. Goodluck!
