NTA... My SO loves make up, especially loves eyeshadow pallets, follows people on IG that put out make up content, it's her thing, she loves it, it's a hobby... I have zero interest in it, but I've bought some pallets for her as presents so I know the cost of them and how difficult it is to get some of them. I also know that not all pallets are equal. I know this because I care about her, and she cares about her interests. If she ruined something of mine through carelessness I'd be pissed, so why wouldn't it be the same her and her make up. Just because it's make up doesn't make it ok to ruin, it's yours and he's an AH for trying to dismiss you
