Not always true. I came from a screwed up and abusive family and it showed me what not to do. It gave me like the perfect picture of a codependent emotional abusive relationship. I saw how both sides were really screwing with each other and how neither of them want to change. Growing up with that crap made me realize what I don't want. Do my parents love each other yes do they hurt each other emotionally yes. It's a sick cycle and they have been doing it for 35 years and both of them are too scared to change it.
