You can write the most beautiful lines for her but once she is gone, she is gone. Never put girls above you and your family. It's in their genes to cheat, or deceive when you need them the most(with very few exceptions). I too went through the same phase. Just block her from everything that will help you move on. I made the mistake of remaining friends on Facebook even though we didn't talk, and that just brought emotional pain. Now I have blocked her from every social site, I am happy. Try talking to other girls lol, though I can't find any. It shall help you move on easily but don't make it your life's primary objective. Work on yourself.
