What is the quickest and least painful way to get over an abusive relationship?

What is the quickest or easiest way to get over an abusive relationship that was verbal, spiritual, psychological and physically abusive? Is there any way to completely get over it or will the person be traumatized (like have PTSD eventually) ?

Will throwing away / burning / tossing out old memories of the abuser make the pain go away faster? For example if you pretend they never existed?
