Have you ever been in love and it went to hell?

OKay I recently lost whom i thought was the love for me! I felt love for her. I really did. But one day she said, "it's over." I didn't understand what the hell happend. BUt I cried for a long time. Cried, cried and cried. Still today I think of her. It's one of those relationships where you don't know what the fuck you did. I'm was so confused. I didn't know what the hell i did. I felt I was attached to her. This is something I never pictured happening. But it did. Out of no where too! sometimes She's in my dreams. well more like every fucking night. I know shortly after the break up i kept dreaming that some day we'd be back together. But NO.. It will never happen..

and it's fucked up!!
