I would say if he refuses to talk, then your friend should sit down and write a letter to him telling him how much he is loved, also that she is feeling a lot of pain as well, because she wants to be by his side, and that once the court case has been, she will always be beside him and will always love him, he obviously blames himself for what happened, he is punishing himself and probably feels he does not deserve to be loved,and he will have to pay the price for that, but at the moment he is also punishing everybody that loves him, he can't turn the clock back although he would love to, he has got to face it, he also needs to go and see his doctor because he could be going into a state of real shock and depression, wish you good luck, take care and hope you can get through to him, Ray xx
