My girlfriend (23F) and I (25M) are about to move in together. We set ground rules, but she keeps violating them.

First of all, I want to apologize for my English as it is not my first language. <br><br>My girlfriend and I have been together for one year now. We are from a Slavic (ex-communist) country, which may be a part of the problem. I've never had a girlfriend before her, so this is my first real relationship. <br><br>We are both adults and she has recently graduated from college. That came with a degree of freedom, since the (ex)communist countries are very strict on university students. No freedom whatsoever, you HAVE to stay in the dorms and have set meal hours. <br><br>My girlfriend is very free-spirited and likes to live life to the fullest. She just completed her studies and now has the freedom to do so, which is one of the problems. <br><br>As we are about to move in together, we had a lengthy conversation about what are the most important things to me, since I'm a man of routine. <br><br>1. **Don't invite random people home.** Not a lot of people have keys to my apartment, and I like it this way. I would only like to have the keys to a few people, which are all of our parents and my best friend. I have a no random people rule, since my best friend has tried to get me to do stuff with random people and I said yes only once, which was the biggest mistake of my life. <br><br>2. **Don't stay out past midnight.** If you're at a friends house, please be home at 12. If you're at a bar, you can of course stay out. But if you're at a friends house, I don't see why you would stay past midnight. <br><br>In less than a week, I was proven wrong. <br><br>First time it happened, I was sleeping and didn't hear the door. She came in around 3 am, and woke me up. I was surprised as she didn't call me to say she would be late. I asked her why she was so late, and she started yelling at me for not being supportive and controlling. I bugged her for a few more minutes, eventually going to sleep. I was tired, and I needed to work the next day. <br><br>Then, it happened again. She was at a friends house and came home at 2 am. I confronted her and she was yelling at me again for being controlling and stuff. I tried to say that she broke the rules we had set, but she said she didn't know exactly when I would fall asleep (I fall asleep at 11 pm). I tried to explain that I just want to be safe, but to no avail. She came home the next day at 4 am. <br><br>Then, something of a bigger magnitude happened. I woke up at 6 am as I had to work, and she was not in the bed. I looked all around the house, and eventually found her in the living room, sleeping on the couch. She was wearing a nightgown and her hair was a mess. I woke her up and asked her why she wasn't in bed. She had no reply. I tried to show her the text she sent me, but she didn't see it. I tried to ask her if she was staying out late to show me who's boss, but she had no reply. I showed her that she broke rule number 2, and she ranted at me. <br><br>After that night, I held a meeting with her and her parents. I told them of all the stuff that had happened. Her mother was on my side, her father was neutral and she was just mad at me for "tattling". <br><br>Since then, everything has been fine, but I still can't shake the feeling that she stayed out late to show me who's boss. It honestly left a bad taste in my mouth. <br><br>Thanks for reading. <br><br>&#x200B;<br><br>EDIT: I wanted to thank everyone for giving me advice. I'll see what I do, but everything is currently fine. She's been sticking to the rules and I've been more supportive of her. Thanks a lot for the help.
