This quote is from the end of chapter 38 in Pride and Prejudice. Elizabeth has just spent six weeks with Charlotte and Mr Collins. She is now considering whether she should tell Jane of what has happened with Mr Darcy.
I think that life is full of these predicaments when you keep something from someone you love because you dont want to hurt them, only to later be blamed for not sharing information you knew. It is very hard to judge what is best in these situations. Overall I think honesty is always best and then everyone knows where they stand. Thankfully for Jane things worked out remarkably well in the end for her and Mr Bingley.
