Faith - I don't know a lot about teenagers, but I actually think that maybe your D14 just needs some space to mull things over and it may take her a few months before she even KNOWs what she is thinking. I would just make sure that you reiterate from time to time that if she wants to talk with you then you are there - if she wants to talk with someone else like a psychologist then you will help arrange that. She is at an age where life seems unfair at the best of times and this is a situation where life really and truly is incomprehensible and unfair for her.
If I hear of any good books for teenagers (or maybe even ones aimed at young adults because lets face it this situation forces teenage kids to deal with fairly adult themes: trust, love, respect, anger, lust, betrayal, honour, loss.... the list goes on...) I will make sure to post.
