AITAH for "stringing him along"even though I knew I was done with him ?

Okay, so I’m only writing this now because it was recently brought up in a conversation, and it’s left me really questioning whether I was wrong in how I handled the situation. I (21F) was in a long-term relationship (about 3–4 years) with my boyfriend (21M). I know that I’m not perfect, but I’m really struggling to see what I did wrong here. So, a little background: we had a huge fight after a really messed-up situation. We were staying in a hotel for a day while i was skipping my classes , and after we slept together, he pushed me down during an argument because I didn’t want to leave the hotel room early that I paid for. (sorry for adding this but it came up in the descision so i thought ui should clarify early on) I wasn’t ready to leave, and I didn’t have anywhere to go for another couple of hours. He planned to meet his friend in the same room, and I wasn’t comfortable with that. He got dressed, left in anger and I was just left alone in this random shady hotel while i was crying uncontrolably. By the time i was able to gather my clothes he had already left. It was the first time anything like that had ever happened, and it was a serious wake-up call for me. I thought it was over after that, but he came back a week later and just told me that he was angry, and that’s why he acted the way he did. No apology, just more of him justifying himself. I told him I needed time to think, but honestly, I knew deep down I wasn’t going to take him back. However, at the time, I didn’t want this whole thing to mess with my exams. I had a few weeks left of studying and didn’t want the emotional stress of a breakup affecting my focus. I also didn’t want to deal with him trying to convince me to stay or guilt-trip me during that time, so I just kind of let him believe that we were working things out and I was still considering our future. I kept putting it off until after my exams. I know that sounds like I was stringing him along, but honestly, I just didn’t want to risk failing my exams or having my career plans derailed. Once my exams were done, I broke up with him for good. I told him the truth about how I felt, including how the incident in the hotel had really changed my perspective on the relationship. He didn’t take it well, obviously, and some of our mutual friends think I’m being a huge AH for "leading him on" and not breaking up with him sooner. They feel like I should have just been upfront with him and ended things, instead of letting him think everything was fine when it wasn’t. But from my point of view, I didn’t want him to screw with my exams or career. Plus, after the push in the hotel and everything that followed, I was pretty much done with him anyway. It wasn’t about "changing him" or "fixing things," it was about me prioritizing my future, which felt more important at the time. I never promised him things would get better or that we’d work things out, but I didn’t feel like I could break up with him mid-exams and risk everything falling apart. I just don’t know anymore if I’m being unreasonable for taking that approach. Was I wrong to wait until the exams were over to break up with him? Should I have just ended things right after that argument instead of letting things drag out? AITAH?

Just adding this cause I didn’t bring it up with my friends as I was unsure. Is it wrong that I felt bad or something negative that he was inviting his friends that he knew I didn’t like very much to a room we just had sex in ? I am not sure how to feel about it but it isn’t good…..
