AITA for getting mad, my boyfriend scuffed the paint on my car

A couple days ago my boyfriend and I were running errands, we had gotten out of the car and when he went to close the door I noticed he was using his shoe to do so. I looked at him like why would you do that and he told me I get upset over the smallest things. I just brushed it off. Fast forward to today, I went out to my car to go to work and I noticed a some scratches right where he had used his foot to close my door. I’m livid. And I feel like I have the right to be considering I pay over $600 monthly for this car (it was a horrible purchase at a dealership). I am in negative equity. And this car already takes a toll on my mental health being the fact I pay so much. He doesn’t seem to be sorry for what he did and his reply to when I sent him the picture of the scratches he said “The paint doesn’t help the car get to your destination. A car is not meant to be resold it’s meant to be used. And Definitely not the only scuff on the car but yeah didn’t mean to sorry “. I just feel like he doesn’t care. Am I the asshole for being upset ?? Or am I being dramatic ?
