I was able to do some forgiveness work around my father who was verbally mean, sarcastic, and critical. I haven't been in contact with him since my mother's death about 28 years ago, but a few years later I just kind of decided to forgive him.
For me forgiveness meant letting go of being mad at him, and it felt like giving him back his own behaviour. It is his mess, his crap, and is all about him and not about me. I separated myself from his behaviour and it felt actually in my mind like taking a big armful of stuff and giving it back to him. All the insults, all the put-downs, all the condescension, all the plain old meanness. It's who he was, not me, and I chose to let go of it all. I felt lighter at once, and I still do. I rarely thought of his hurtfulness after that, or of him.
I still can remember the way he was if I really try, but if I think of him now I do so without much emotion---just someone I knew long ago who was a mean person. The memories of him are dim, and don't hurt any more. I don't feel like I'm dragging around a heavy load of bruises inside my heart from him. I took them into my arms and gave them back, saying in my mind These are yours. I won't carry them any more. I know you did the best you could at the time----it was pretty poor, really. So now I let you go.
Now. I am still working on my mother, who has been much harder and more stubborn to get rid of. Maybe because I spent more time around her, maybe because I expected more of her, maybe because she was just more poisonous. But I am working on it, because I have had MORE THAN ENOUGH of carrying around her poison---in the form of memories that still hurt----for 50 years. But I want to forgive that woman who was so trapped in her own quicksand and could not get out. What a miserable person she was, and she spread it around to all of us. What a miserable life she led, and then died, still full of poison.
For me forgiveness does not mean excusing or saying it was okay. It means understanding that these mean-spirited and abusive people could not do any better than they did----did not have it in them to be better, and did not make better choices. And that's their crap, not mine. It means letting go of the anger that has bound me to them so tightly. Why they were like that I don't know, and I don't care why any more.
I recently said to my therapist that it feels like I've been rowing this little boat all my life with a rope out the back towing more and more baggage as I go. And now there is so much that I am unable to move forward any more and I am stopped dead in the water. So I am working on letting go of all these pieces that weigh me down. My father's meanness, my mother's abuse, my boss's death, the way I was treated at work......opening my hands and my heart....and letting go. Hopefully I will be rowing forward one day soon.
