Kelida-(Firmly ignoring thread creep and unkind sentiments...) Have you evern heard Christine Lavin's song, What was I thinking? Or Dar Williams' wonderful tale, which I recall having a long name and I have stupidly forgotten, about her leftist cannabis smoking boyfriend in college?
As for robber bride songs... this isn't strictly one, but I'm thinking of "Step it Out, Nancy"... now there's a woman who made her revenge. Or even Frankie and Johnny...
Relationships are the stuff music is made of.
