AITA for not letting my friend borrow my car after she stranded me the week before?

I (18F+) have a small, close friend group, and we usually have each other's backs. We take turns driving places, splitting gas, that kind of thing. I’ve let a few of them use my car before (with me in it or not), and it’s never been a big deal—until now.

Last weekend, one friend offered to drive us all to a concert about 45 minutes away. I left my car at her place, and we all piled into hers. The plan was to hang out afterward, then ride back together. But near the end of the night, she met some guy and decided to ditch—literally just left with him without telling us. I only found out when she texted, “Hey, I’m crashing at his place, you’ll have to find another ride.”

We were stuck. One of our friends had to call her older brother to come pick us up, and I had to Uber back to her place the next morning to get my car. It was super inconvenient, and honestly? Kind of disrespectful.

Fast forward to this past weekend—she texted me asking to borrow my car because hers was “acting up” and she had a date. I said no. She got super passive-aggressive about it, saying I was being petty and holding a grudge over “one mistake.”

Some people in our group are split. A couple agree she shouldn’t have left us like that in the first place, but another said I was being spiteful and should have just helped her out.

So… AITA for not letting her borrow my car after she stranded me?
