Do yourself a massive favour and stop using forums for personal problems and use Citizen's Advice instead. At least there you will not get arrogant and **** take responses from people still living in mummy's basement.
I'm not sure American stereotypes apply that well to a mostly UK forum... its especially odd if you're actually from a part of the UK. Do many houses over there have US style basements? IME they don't tend to over here on the mainland.
Suggesting a flat share is hardly arrogant - its what lots of other people would do or did do in his situation...
