It's Not Me, It's You! is a book written by English comedian Jon Richardson based on his 2011 comedy show of the same name. It was published in the UK by HarperCollins on 23 June 2011. Richardson has said "it is not an autobiography" but rather it is a "relationship guide from the point of view of someone who hasn't been in one for eight years".[1] The book began as an article in The Guardian newspaper's Weekend Supplement Valentine's Day issue, that was printed on 13 February 2010.[2]
