I have a family member who to me and others is in a narc relationship. He provides money wise but he does nothing else. She is effectively a single mum. She now has no friends and is very cut off, only goes outside when he is home. They have been together for over 10 years. She is extremely insecure but no one can get to her anymore. She is happy to live like this and says this is all she has ever dreamed of. Do some people just live like this forever?
