I don't necessarily think that this song has much to do with a failed relationship.
I think this is about a person who feels the need to change their life. They are stuck somewhere with no chance of moving forward and now must make the choice to force that change by doing something drastic.
The lines 'let it rain' are their wish to be cleansed of their past and their fears and their so-called-sins, and be given the courage to do what they must do.
While I agree that there is an element of the speaker having stayed where she is because of someone else (someone she felt strongly about), I don't think that is the only thing that she needs to change. I think it's her life, in total.
