Why it’s unhealthy: The relationship at its centre is almost radioactively toxic
‘It really shows how two people’s toxic ideas about themselves can reinforce each other, creating a kind of co-dependency hall of mirrors where your own delusion is supported by the other person’s delusion. The two inflated egos back up each other, so all the fragility that’s hidden underneath a big ego never gets addressed as they stay in their shared fantasy. Hence the folie à deux.’
