Here is another song from The Civil Wars.  I love how it captures that feeling of wanting desperately to trust someone you love, but knowing in your head that something is off.  It is very fitting for the relationship Liliana has with the men in her life.  She loves them, but she also doubts them.  It's hard when you really do know better.  That, I think we can all relate to.
