Hi Dan
I wouldn't be accepting blame here.Hopefully your Girl friend heard him admit that he was in a rush and late for work, so really he wasn't paying attention..He should of given you plenty of room to leave the exist, found that info on

Like the others have told you, get in touch with your insurance company and tell them everything, even to the claim that he is making that he was injured...
I personally think he should of given you his details like his insurance company and his name and a contact number, as he hasn't complied with the Road Traffic Law, that is required if your in an accident.. I wouldn't contact him just let your insurance company deal with the situation ...
A few years ago I was hit from behind on a roundabout and the guy who came into me was shouting 'Why did you stop'? Said because the light was red! we exchanged details and he lost the case...
Good Luck with this
Cheers
