I don't know if this will help or not, but sometimes we relive certain memories of the abuse to better understand them. Understand probably isn't the best word, maybe more like "see the reality" of what really went on.
The rose colored glasses we wear in an abusive marriage or relationship are gone now, and we can see memories with new eyes. I know for me, in my cesspool of a marriage I was in survival mode 24/7. I became numb to his verbal beatings, and was wore down to nothing by the time he left me for some floozy. He only touched me once in anger, but it was enough to keep me in fear for the rest of my years with him. It was his unique knack for making me feel like a worthless piece of sh*t that took it's tole.
Every haunting memory I'd pick up in my mind and examine it.. tear it apart. I think for me it was to see who he really was, a monster in a human suite.
