I read another woman’s post that that’s exactly what she used to do with her children. She would try to soften the abuse by taking over from her husband and making him feel that he had won, so he could quit. Then she would do as little as possible herself. At the time she felt that it was the best she could do, but now a while later (after having gotten out) she realizes how twisted the whole thing was and has a lot of remorse and guilt.
But it’s really hard to recognize when you’re in it.
An old friend of mine described once how she and her siblings would do something similar; if Mom was going to beat one of them, they’d ‘help’ by getting the least-painful belt and so on, but there was also an element of buying in to the whole thing. Of course, they were children, and they don’t bear the same kind of responsibility, but she had similar guilt over it.
