Please listen to this video and keep it in mind what actually occurs in the victims. No two people feel the same way, but you are under no obligation to forgive an abusive person. Morally,speaking, I have never and will never be put in the position of forgiving an abuser. My mother was an overt narcissist and everything was her way or the highway, no one had the guts to stand up to her except me. An extremely destructive individual and she knew exactly what she was doing.
Such an individual will break you down and make you think it is your fault and in some cases will do the accusations in front of other people; who will be too afraid to defend you. You do not owe either the abuser or enablers any apologies, remember that.
