There's a girl I'm dating, we seem to get along and are getting pretty close. She tried to arrange having me come to her sister's wedding afterparty, but due to logistics and everything it wasn't completely guaranteed that it would happen. The day of the wedding, she messages me saying to come by. Now, this is a big deal to me since this would be the first time meeting her parents and family. In addition, I knew absolutely no one at this wedding, so you can imagine how that would give me some anxiety. 

When I arrive, it's past 9:30, the dancing seems to have peaked, with the first guests starting to leave. Everyone is quite drunk, I tend to shy away from tons of alcohol. The girl I'm dating seems drunk asks me to bring her a drink, which I do. She then asks me to bring her a drink two more times, after I say things like "you sure?". I'm feeling a little strange since I've never seen her drunk before and she's behaving quite differently. In addition, I've had some really shitty past experiences with an ex who was borderline verbally abusive to me when drunk, and I just wasn't feeling it that night. 

 I spend about an hour dancing with the family, bride, and whoever else hasn't left yet, and then I tell her I'm thinking of heading home for the night soon. She straight up tells me I can't leave, and that she will get really upset if I do. She then asks me to do some random tasks which I do, like moving wedding supplies into the car and trying to stop the dance floor from dying out. I try to leave a few more times, but she makes it clear that it's going to be really bad if I leave. I end up leaving at around 1:30am. 

The next day I told her that it was weird of her to force me to stay when I wasn't having a good time, and that she should be fine without me there since all her friends and family are gathered at the wedding, whereas I knew no one and it was a weird atmosphere to meet the family. She said that arriving and wanting to leave so soon isn't something you do. I'm not sure how to respond. AITA?
