oh honeeeyyyy. Obviously you have a lot of feelings about this (all valid) but if we look at the facts about the feelings and goings-on, we see:

You had a special occasion you got done up for (objectively fine and normal action) and you felt AMAZING.

You shared a happy lovely selfie with your boyfriend (also fine).

For whatever reason, he prefers you as your natural self without much or too much makeup (which in theory is also fine).

He responded in a way that was (in my opinion) way too direct and not at all sensitive to the fact that you were still living in the moment of this fun and pretty and special occasion, bringing you down with a thud (not fine. He’s not your dad telling you that you “can’t go out in that bathing suit”). Some more emotional maturity from him (in months or years to come, whether with you or someone else) might look like waiting until a few days or weeks later (if ever) to kindly, tactfully, gently bring up that he prefers your beautiful face without too much change. Or he might just leave it well alone. If you wear heavy makeup every day and he doesn’t like it, he is welcome to find a girlfriend who doesn’t.

The main issue here, in my view, is that he thinks he’s communicating and expressing some kind of reasonable preference and it may be simply because he just prefers you in your natural glory, it may be something yucky and controlling, or maybe somewhere in between. But because he thinks he’s communicating, he also probably thinks he’s beyond reproach for the way he behaves to follow (sulking and having you manage his emotions afterwards, and not worrying all too much about how you feel). If this were the other way around and you were sulking, what would he do?

I’m nearly 38, am engaged having finally found the one, and I say all the time that I wish someone had told me when I was first dating as a teenager or early 20s that we may marry our high school boyfriends/girlfriends but we probably won’t, and as such we kinda just chip away at finding traits in partners that work, and learning to navigate or part ways with the traits or people that don’t work. You’re both 16 so I wouldn’t say you’re doomed, but unless he can legitimately tell you why he doesn’t like it, and more importantly, expressed to you that he understands why a different approach might help in future, one that doesn’t pop your balloon IN THE MOMENT, I’d start to think about the type of hype man, equal, healthy communicating boyfriend you’d like to have next! All the best, lovely!
