thank you 
i have to say i was very cautious to begin with knowing how when stressed his perceptions get skewed, but ive checked it out, as has his named advisor, and its true. He made a report straight afterwards. He is feeling ashamed, upset, vulnerable. He didnt see what was coming because he does not read people due to his aspergers.
The disability team have arranged for the liason officer for the police to speak with him on tuesday. Im trying not to be 'police officer' with him and just mum who will sort it all out.
He is stressing. Ive spoken to him several times. He cant concentrate on work that is due in, and feels guilt that he did nothing while being assaulted.
Ive worked with rape crisis through work, so was able to explain "fight, flight, or freeze" but its so hard, and he cant accept it.
He just wanted to come home, but if he does he will fail his degree.
im still level 1.....came off nights this morning, feel disoriented and groggy and then he rang crying and pleading with me to go and get him....which i cant do, he needs to speak to police/uni/safeguarding team about this man, because DS has not been the first, but the first to report it.
he is a brave to do so, i just wish he had talked to me first. im ok i think really. ill call him again in a bit. he is just bewildered.
