I am heartened to hear that your F-I-L is setting up the rules of the house. Too freaking bad if she doesn't like it. Boo hoo. I hope he is steadfast in this. Not mind reading but I think that has to be a some sort of reality check for her. I can't help but wonder if she thought that her parents were just going to do wheat her GF's mom did. Heck, they have their own life, too.
Good job on not assuming anything on her end. Until the words come out off her mouth and the actions dictate otherwise, you should just consider the situation unchanged.
