I've been dating my girlfriend for over year now and I really do care for her. The only issue I have is her two children. One is 12 and the other is 10 and basically they're monsters. They show no respect to anyone. They're rude, loud, confrontational and all around bad kids. I know its not my place to say anything, but at what point in a relationship can you put your foot down and discipline kids that are not yours. How should I go about this? I don't want to step on my girl's toes on this, but something has to be done.
