do not feel guilty, as W~M says quite rightly, they are the only felons! You would not have let ther walk alone if you had known what would happen to her. No way could you have forseen such a terrible thing. It only happens to other people doesn't it! Can you imagine the guilt her boyfriend is feeling right now. Guilt helps no-one, whats done is done and no amount of guilt will change that. She has her b/f to support her and you will be there for them both should they need you to be. You didn't do anything wrong!!!! A lot of women like to remain independant and refuse mens offers of walking them home. She just happened to be in the wrong place at the wrong time.Try not to let this affect you too much, she will need you to be strong! Good luck
