My love, in our last conversation you said I should take better care of my skin. You added, ‘It’s only because I’m thinking of you,’ but that really upset me. I’m already trying a bunch of things for my acne, but it’s not completely going away. Is it normal for him to think so superficially, or am I overreacting?
To me, the issue isn’t the acne, it’s his attitude. That part about “I’m just thinking of you” feels like he’s trying to control you. If you’re already doing everything you can for your skin, this might just be his excuse.
I mean, the thing is, your partner represents you in public. Plus, let’s not normalize dealing with acne at this age. I don’t think it’s exaggerated to be concerned about these things; everyone pays attention to their appearance 
Look, acne can sometimes be a hormonal or genetic issue. If it’s beyond your own efforts, you should see a dermatologist because it could be a completely medical problem. Instead of withdrawing support, your partner should be involved in this process.
Let me add this, it was like she said something like ‘the thing that would suit you the most is smooth skin’, she talked all sweet like that. As if I don’t want to be smooth. To be honest, I’m still sad, but breaking up for this reason seems really silly.
It’s important to start with a dermatologist to find out the reason. If it’s something hormonal, you can also get in touch with an obstetrician. But when talking to your girlfriend, make sure to clearly state, ‘I’m already looking for a solution.’
