AIO about my boyfriend returning to the party after a stressful situation?

My boyfriend (26M) rejoined the party after my (28F) car got towed; We've been together for 2.5 years. I attended my boyfriend’s close friend’s birthday and parked my car in the visitor spot at his apartment complex, which got towed around 8 pm. My car notifies me when the alarm is triggered, so my boyfriend and I ran outside to check on it and saw that it was gone.

While I was calling the police, he called the towing company listed on the sign before entering the parking lot and found out where my car was. He learned that the cost would be around $500 and offered to drive 20 minutes to get it.

As we were driving, I was sitting in silence because I felt really bad about messing up and having to pay such a large amount of money. I was already bummed and did not feel like going back to the party at that point.

When we got there, I paid for the car. My boyfriend offered to Zelle me $200 because he felt it was partially his fault for not checking with his friend and asking him to add my car to the visitor pass. I was really thankful, but still sad because I do not have a job at the moment, and even $300 is still a lot for me to pay.

After getting my car back, I asked him what we were going to do next. He said he wanted to go back to the party since it was one of his good friends and he did not want to miss it. I said I wanted to go home. He thought I meant his home since I live an hour and a half away, but I clarified that I meant my home.

He asked if I needed anything, and I said no I would just go to his place, pick up my things, and drive home, so I drove away. On the way to his place, I was already sobbing. He called me and offered to come with me to help me get my things.

By the time I finished packing, I could not stop sobbing, it was such a stressfull situation that ruined my entire night. He helped me load everything into my car, hugged me, tried to console me for a bit, then waited for me to get into my car and drove away very quickly before me.

I am really grateful for his help with driving me there and paying for the towing, but I also felt weird that he went back to the party so quickly and without me, especially when everyone knew what had happened. I just felt like he abandoned me and cared more about having fun.

It happened before when we were celebrating our first New Year’s. I got sick, and while his friends were celebrating, he left me home alone with a fever and went to his friend’s house.

I do not know if I am overreacting or being selfish, or if what he did was normal and I just have to get over it.
