I know you are feeling blue, but ... if you are feeling a little vindictive I would suggest some early Richard Thompson, i.e., shortly after he split with Linda. There are some VERY biting lyrics on how he thought about her. He was probably a little harsh, at least for a public forum such as a song, but that is how he felt. I'm not advocating hostility to an "ex" just some good music inspired by such an event.
