Cover art for Liar lyrics by Mumford & Sons

Honestly, I can only go on what this song makes me feel he is saying, but its like the person he loves is telling him she was unfaithful to him, and she begins to cry... the singer is almost disgusted by this, she was the one that wronged him and not she is crying, its almost unfair. (The way he says "you liar" is why I think this.)
