So I just moved in with my gf into her parents house. My parents divorced so I had nowhere else to go. I'm only paying the difference in bills. Her and I have been dating since high school so she's known me for quite some time. I love watching sports, playing video games, drinking, and just having a good time. Now that we live together, she's always nagging me. I'm getting yelled at right now because there's a NASCAR race on that she knows is on every Sunday. I had a beer the other night after work and she immediately freaked out and said I'm an alcoholic. It was 1 beer. I just bought a new video game that I've been playing for an early release weekend. So I paid extra to play it. She's been busy going shopping with her mom. She doesn't tell me when she's coming home. So when she shows up and I'm in the middle of a game, it's my fault that I didn't know when she would be home and that apparently means I'm ignoring her. I just don't know what to do here. We had a conversation about this a few times and after she's done crying for almost an hour she finally agrees that she was wrong or that she got mad for nothing. I've only been living here for 2 months and I just fear that it's going to continue to get worse and just lead to an unnecessary altercation every weekend. I'll also mention too, the way their house flows is very bizarre. Her dad doesn't really have any responsibilities except for taking the trash out and mowing the lawn. I do what I am asked. The girls basically do everything. So it's not like I'm bumming it out here or not being cooperative. I actually feel like I do more than the dad. I make my own food or I'll help make food and I do my laundry. If I need something I get it myself. He just asks the girls to get him stuff. I'm just at a point where we've had these conversations multiple times already about my hobbies that I've had (sports and video games) my entire life and she's still expecting me to just drop them all. Idk if I should continue this or look into moving myself out.

Edit: I've gotten a few comments about doing more chores. I may have misspoke my words a bit. I do chores and I do what is asked of me. I don't live here like a slob. I've actually been much more clean here than I was when I lived with my parents. The main issue I'm having is that all of a sudden my hobbies are a problem to her.
