Cover art for Various Storms & Saints lyrics by Florence + the Machine

I think she's singing to someone (possibly herself) who has had her heart broken and blames herself for falling for that person in the first place. She wanted a relationship with this man, but when it became toxic and eventually ended she felt broken. She can't forgive herself for the end of the relationship, regardless of whether or not it was her fault.

In the chorus, Florence seems to be telling this person that, while she may have made a mistake and may be hurting, she needs to learn to forgive herself and move on. She may be talking to herself, trying to convince herself to let go of the guilt from a broken relationship.

Her voice is amazing in this song, and I love the subtle arrangement. Great song on a truly great album.
