Whats a good song when you love a girl but she breaks your heart in the worst way imaginable?

She asked me out we have been dating for awhile ive shared all my feelings with her than she has me call her ex and he tells me they are going to go out then he hangs up I call her she laughs at me than hangs up. She lied the whole time she is the only person i have ever loved and I still do but now im thinking about suicide.
