Madeleine L'engle said this quote

Emily looked over at Courtney. He was still asleep. For a long time she had thought that if you loved anyone you had to tell him everything: go to him and confess as in the dream; there could be no secrets. But now in the dark of early morning with the copper bottle cold against her fee she felt that this desire to tell all was simply an evasion of responsibility, a weakness in wanting to push on to the person you love something that is your own responsibility to solve. It would be easier for her to tell Courtney all about Abe, to come to him as he sat at this desk in the chill little workroom and confess, to hand the responsibility for her ambivalence to him, to let him settle the problem of her puny conscience for her.But I know, she thought, lying there beside him on Madame Pedroti's lumpy bed, that if I love Courtney that is the last thing I must do. If I love Courtney he must never know.
