What sort of rules are you talking about, Lucy? I think you would be running a big risk by cutting loose - our bf's parents might be welcoming, but it could be very different if you are living there, particularly if you and the bf split up in the future. It could cause big divisions between your parents and his. I'd think long and hard before you do it. Can't you just study at their house where it's peaceful, then come home to sleep? You might not have to pay rent but you would surely want to contribute for food, laundry etc., how would you pay for that?
