AITAH FOR THINKING ABOUT BREAKING UP WITH MY GIRLFRIEND OVER MY SELF CARE HABITS?

I (24M) am a last-year medical student, and I'm really passionate about taking care of myself.

I've been dealing with acne and oily skin since I was 16, so I've had to work hard to develop a skincare routine that works for me.

I have a care routine and I stick to it. Since I don't have much time in the weekdays I have a small but effective routine and I go all out to pamper myself in the weekends.

I also take supplements and have a good diet plan. I hit the gym daily after college and since is in good shape.

I see a dermatologist regularly, and I've had multiple skin, body, and hair treatments over the years. I've also developed a bit of a habit of collecting men's perfumes - I've got 22 of them now.

I don't do makeup, but I do have a conceler, loose powder and some eyebrow/lash stuff which I use only for special occasions.

My girlfriend (23F) is also a student at my college, but she's a year younger than me. We've been dating for a while now, she's been giving me a hard time about my self-care routine.

She thinks I'm being "feminine" because I take care of my skin, shave my body and face every two weeks, and use lip balm and sunscreen regularly. She's always comparing me to other men she knows, saying that they're "real men" who don't do this kind of stuff.

Yesterday was the final straw.

We were hanging out with a group of friends in the canteen, and one of my friends asked me for a lip balm recommendation.

My girlfriend laughed and turned to the whole group, saying "Looks like I'm dating a woman."

My best friends stood up for me, telling her that there's nothing wrong with taking care of ourselves. But I'm still feeling pretty hurt and frustrated.

Am I being unreasonable for considering breaking up with her over this? Has anyone else dealt with something similar?

Edit:- Ok, I think I need to tell you a little about the make up part- I study long hours and have dark circles, a cousin of mine who is also a makeup artist encouraged me to get a conceler and a good setting powder.

I know lot consider it 'feminine' but I don't want to look dead in photos and special occasions with my lack of sleep.

I was initially hesitated very much about it but decided to get one for special occasion/date/ for the days that I look almost dead. What I want to say was that I don't have extensive makeup routine.

Also, my sister shaved my eyebrows when I was 15 becuse I took her chocolate back then.

I have been trying to get it to grow since then. But God damn that shit doesn't grow easily.
