my bf (21M) got mad at me (20f) for asking him to keep driving, wtd?

earlier, me and my bf went for a stroll around the block to find something i’m craving for. he wasn’t really into any snack, and i’m the only one who wants to eat a specific food but not really hungry or into it real crazy. he saw a stall that looked like it was selling what i’m craving for, but turns out it was different. as he slowed down, i suddenly see an old friend i don’t want to cross paths with anymore. and so i told him to keep driving as (1) i don’t want to see that ‘old friend’ anymore, and (2) that’s not the food i’m looking for.

he got mad at me for being bothered about the ‘old friend’ being at the same location, and me acting crazy. it’s like he’s implying that i shouldn’t care, and as much as i don’t, i just don’t wanna see that person anymore. he didn’t talk for hours because of that, and i think it’s petty and toxic. i didn’t even pressured him, pull her shirt, or did anything i’d think he’d be mad about. i just told him to keep driving, then he suddenly lashed out, became aggressive, and his tone of voice was high. it turned me off, so i ignored him. he still hasn’t talked to me, it’s been 4 hours.
