Fay Weldon said this quote
“ Lucy could see that love unconfined, love outside convention, might well make a woman an unfit mother; you were one kind of woman or another: you were good or you were bad, as the world saw it, and no stations in between. They allowed you to choose; you could be the maternal or the erotic, but not a bit of both. The latter made you forget the former. Men married the maternal and then longed for the erotic. Or they married the erotic by mistake, and set about making it into the maternal, and then were just as disappointed. ”
