i’m starting to see my face as more of a woman than girl

it’s so weird whenever i get ready to go to an event of some sort i look at myself in the mirror and think “wow im starting to look like a woman”. today i told my boyfriend “oh my god i look old” and he pointed out that im just looking more mature now which is true and kind of cool but definitely weird to see. i know it’ll continue as i get older lol but wow
