I'm familiar with that quote and you hit it on the head. When you come to realize that the forgiving sets YOU free, and has little to do with her, you'll be on your way.
Read up on Forgiveness. It's not something we all just know how to do. We confuse it with condoning or loss of self respect, and it's neither. Forgiveness/letting go is what allows us to unburden ourselves, and walk straight up & forward, without any baggage or chains.
