So just that really. It came out a few years ago that a very good friend of mine was one of those people who fakes an whole online existence under a fake name.
She had a whole parallel online life that bore very little resemblance to her actual life. She seemed to hit most of the tropes including a twin pregnancy (always twins!) and then claimed her 'husband' had died suddenly while she was pregnant. It absolutely destroyed her online and offline friendships and she ended up leaving our part of the UK completely to try to get away from it. Anyone have any questions about what it's like to realise your friend has a whole false life?
