Oh well!
If she doesn't want you, she doesn't want you. There are 4 billion girls on this Earth .. you don't need her.
You shouldn't hurt yourself over one girl .. You're a guy. Start acting like one .. Don't chase after one girl and spend countless nights thinking about her when she's probably on top of the guy she dumped you for.
Relationships begin and end every day. Move on and play the field ..

To answer your question, no, I never have been. Don't get me wrong, i've had girlfriends and bad friends, but I don't let the stupidity and ignorance of others effect my emotions and mood ..
I have felt disappointed, and I have felt ashamed .. But my heart has never been broken by anything someone other than myself did .. :[
