I have sometimes said to a client: “If you are so in touch with your feelings from your abusive childhood, then you should know what abuse feels like. You should be able to remember how miserable it was to be cut down to nothing, to be put in fear, to be told that the abuse is your own fault. You should be less likely to abuse a woman, not more so, from having been through it.” Once I make this point, he generally stops mentioning his terrible childhood; he only wants to draw attention to it if it’s an excuse to stay the same, not if it’s a reason to change.
