How to help someone with narcissistic parents...

Throughout my fiances upbringing he has always been the scapegoat. He's 28 and is a bright and loving person but his family doesn't seem to care aout his wants or needs. Nothing he ever does is good enough and he is never right. When he stands up for himself or tries to do something other then work for the family business he is belittled and they use guilt to get him to stand down and do as they want. They want him to leave me and work over 60 hours a week for under minimum wage as he lives under them and their rules. He's so use to them using guilt trips saying that he owes them, that he has to take care of them and do as they say or want. He's so use to trying to get approval from his father that he feels he isn't strong enough to defy him. Yet at the same time he is miserable and knows that if he does what his parents say that he will live a life full of regret and hatred. It's not like he doesn't see what they're doing is wrong but at the same time he's been brainwashed to think that he owes them his life. Poor man has been abused for years emotionally that he breaks down with guilt every time he tries to stand up for himself. Is there anyway I can help him? Is there anyways I can help show him that he is a person with options and that he can break the cycle?

Can I suggest you get a copy of Toxic Parents by Susan Forward - it's a very good book.
