Hmmm, she will need your support as she wont get much from victim support.
From someone i knows experience they do get a little annoying after a while by some of the stuff they say.
I think you should pop round as much as you can and support her too. She wont be in any state for talking to her boyfriend properly yet. Try to have a word with him seperately also and tell him not to question her about the ordeal.
I dont know if they live on their own or not, but if they do, it might be an idea to stay with her for a couple of weeks if its possible.
Like Ethel says above, victim support are there for both of them though , and it will affect both of them , no matter what he says...
