AITA for coming to dinner basically expecting a free meal?

My boyfriend(25M) and I (24F) are first year medical students. On Wednesday, my boyfriend called me as he was excited to share that he got his first ever student loan disbursement and wanted to celebrate. Because of the way my loan is set up, I usually get my disbursement on the 25th of each month, so I already had my money for this month. We decided to go to a restaurant and pay out of our own pockets. We got to the restaurant, ate and had a few drinks. <br><br>I’ll admit that because I’ve been going through a really rough patch, I had a few more drinks than I usually would. Before we even got our food, I was pretty tipsy. By the time our food had arrived, I was already drunk. As much as I hate to admit it, I was a hostile drunk that night. I remember getting angry at the waiter and snapping at my boyfriend. I also threw up on the table. We just left and he took me to his place, where I continued throwing up in the bathroom sink for the rest of the night. <br><br>The next day (Thursday), I felt so bad about what I did. I called him and apologized profusely, but he said it wasn’t a big deal. He said he would pick me up at 7:30pm and take me to his mother’s house for dinner. I asked if I could stay home, because I still didn’t feel well after drinking so much. He said that we had to go, because his mom was expecting us and that we were celebrating his loan again. <br><br>I don’t know why my girlfriend brain decided that this was a free pass to just go to dinner and eat for free, but it did. I didn’t make any effort to be a good girlfriend the way I usually was. I didn’t even dress up. I put on the same dirty clothes I wore the night before. I went to his mom’s house and just ate. I didn’t help or lift a finger. I barely talked to anyone. I didn’t even say please or thank you. I just shoveled the food into my mouth. My boyfriend’s mom kept giving me weird looks and my boyfriend was angry, but I didn’t care. After dinner, I left and went to my apartment. I didn’t even help with the cleaning. <br><br>My boyfriend called me and was yelling at me. He said that the way I acted was extremely disrespectful to his mom, who spent her whole day cooking and preparing dinner. He said that I was rude to his family and that I didn’t even say thank you. I told him that I could act however I wanted since I didn’t ask to be invited. I also said that they should have expected me to act like that if they invited a drunk girl to dinner. He hung up the phone on me. He’s not responding to my calls or my texts. I feel like I might have been an asshole this time, but I’m still expecting an apology from him.
