We have been together about a year, and during the summer she was going out a lot. I was cool with it as I hadn't heard anything bad about the places she frequented and I didn't have any bad experiences with her going out in general. But recently a few things have happened, like her and her friends being assaulted there, finding numbers of other guys in her phone texting her after a night out saying how fun it was to dance with her and how they wanted to see her again, and me having to clean up after her messes when she throws up everywhere. This all made me more apprehensive about her going out with her friends. Every single time they go out by 9pm and typically don't come home until 2:30 or 3 in the morning. I've gone with them a few times but most of the time it's just them. Every time something bad happens, we get into an argument about it and I'm the one who has to get over it and she just ends up going out again in a couple weeks (this has happened at least 4 times) I've expressed to her that after the most recent incident I'm not okay with her dancing with other guys or her getting their numbers. But I have no way to know if she's actually doing any of that. Her friends would never tell me what actually happens. The most recent time they went out I tried to come along and she blew up like I was being possessive and over bearing, and it turned into a massive fight. I don't like dreading the weekend waiting for her to tell me that they are going out and I instantly start worrying about her. I know she values these nights out very highly and sees it as a way to be independent. I don't know what to do. I don't want to tell her to stop going or we can't be together, but at the same time it's driving me crazy worrying about her. I've told her I don't like that they stay out so late or come back so drunk but she avoids the topic. I just feel like I can't ever know that she's 100% safe or being faithful while she's out so late. I have no idea how to handle this, It's not something I've ever had to deal with before. I'm unsure if I am the asshole if I tell her I don't want her to go out anymore. I just want to not worry when they go out or not dread hearing that they are going out this weekend. AITA if I tell her to stop going out?
