Here's a question for all. Does she have the right?

I have been with my common-law wife for more then 7 years living together in a bungalow. Then we sold it and moved to a duplex. I did all the painting and repairs myself. My spouses daughter from her previous marriage is a very and introverted conservative woman at 30 years of age. She has hared me for 6 years about the TV volume since I gave her the choice to be in the room next to the living room when we moved in. This girl is a psycho when she gets into her nervous tantrums yelling and screaming at all hours of the night dragging her family in on her stupid hissy fits. Her brother who's a giant, her grandmother who is 86 her mom who is with me and my patience running out fast! Is she selfish to keep asking me to lower the volume of the TV if she is always in her room secluded in solitary silence and away from the world? Does she have the right morally to tell me after all I've done for her (painting and repairs in 2 houses) that it's HER HOUSE! It's my house! Is that not just absolutely SELFISH? I called her selfish, self absorbed, snotty, stuck up little snot. She always had the good life before. Now she has ME arrested because I smiled one night to myself and she got paranoid as usual and aulted me with a gl of water while I was sitting on the couch! Does she or doesn't she deserve a mive beating after all this? Just a question that's all!
