<human>: I was driving to lunch today with 3 of my friends (we work in the same company and have known each other for 2-3 years). After I parked, one of my friends wasn't paying attention and bumped the car next to mine with her door. There was no visible damage. She brushed it off as not being a big deal because there was no damage. I was annoyed at her carelessness and nonchalance and told her that I thought that she should apologize for not being more careful. She didn't think that she did anything wrong and refused.

After lunch, I told her that she was unwelcome in my car, and the four of us got into a big argument, with my other two friends (one being her boyfriend) convincing me that it wasn't a big deal. I told her that I didn't care about any damage but that I thought it was disrespectful for her to not care about my property. I also said some other things that I'm not proud of. Her boyfriend and my other friend stayed with her and called a taxi while I drove off.

I realize that I was being petty, and that I overreacted and behaved as a crappy friend. I plan to apologize to her for treating her like that regardless of the circumstances that led to it. That said, I feel like the initial issue won't be resolved because she's unwilling to acknowledge any fault of her own. Is she at any fault? Should I just drop it?

Condense the text into a few key points
<bot>: Overreacted, ditched friends and drove off by myself because I thought one was being disrespectful. I plan to apologize, but I doubt she will apologize in return. Should I just drop it?
