I think I lived with a few. They are very good at making you feel everything was your fault. And not reacting to a thing when you beg forgiveness or show fear. But if you decide you have had enough and decide to leave and they need you for something, they will play the I love you need you card even beg sometimes succeeding in somehow making it your fault until they don't need you anymore, or they realize you are serious. Then they just walk away like it doesn't matter. Like you never mattered
