The Past Will Not Be Different.
When I read, "the past will not be different" my first thought was, "That's stupid, of COURSE it won't." Then I realized I really WANTED it to be different and used a lot of energy wishing for the impossible. It was what it was. There was pain and loss back there. I decided to not deny, rationalize or minimize it, but rather to turn and look it in the face and grieve and get it over with.
I wrote down how a moral contract was broken, who was responsible, and chose to forgive and go on. It was painful, but healing. It really happened. It really was bad. Someone was really to blame.
It was what it was.
