This, ^^^ there comes a time when you have to stand your ground with overbearing family members. Been, there, done that, got the tshirt. My grandparents weren't very happy with me. I was 20 and living on my own and put my foot down. Everything didn't have to be to please them, it was now what I wanted. It may be awkward for awhile, but you will find yourself probably happier, if you tell her these are things you like, a hobby you enjoy very much. And while she is entitled to an opinion, she can keep it to herself when she is in your home or around you, as you have heard enough of it. Good luck. :)
