No mean person is mean all the time. The whole point of being mean is to fluctuate so that you can hold out the hope for someone. So someone will hold out the hope that they're gonna catch you on the sunny side or that you're gonna be nice this time. The tyranny is inconsistency. Somebody thats consistently mean is something that is pretty easy to sort out. The reality is that the meanest people can be wonderful sometimes. That's the whole point of meanness because otherwise it's too obvious. It's the niceness that gets you trapped in the dysfunction. That is the problem and so the fact that you have this belief that there is hope in the relationship is foundational to the dysfunction.
