The parents are out of the picture, she lives with her grandparents.

Unfortunately, as long as she lives with her grandparents, she has to abide by their rules. It's their home, hence It's their way of living for everyone under that roof.

But once you both get a place of your own, no one (and I mean "no one") can tell you what you can/cannot do In your very own home. I had massive Issues with my ex-partner's family, namely the parents. Initially, out of respect, I didn't day anything but once It became too much, I simply told them that I'm the master of my domain and they have no right to dictate any happenings In my place of residence.
