AITA for not wanting my roommate [21F] to bring home her random hookups during a pandemic?

I’m feeling very disillusioned with my roommate right now for various reasons, but this is the last straw for me. I need to know if I’m being unreasonable. Background is that I have a boyfriend, my other roommate has a boyfriend, and the roommate I’m discussing in this post is single.

We are experiencing a large spike in COVID cases where I live, particularly in variant cases. I’m feeling very nervous about it since I’m an asthmatic, and because the roommate in question is immunocompromised. Technically, we are in semi-lockdown, meaning that we can’t see anyone inside, but we can hang out in groups of 10 or less outside. Our boyfriends are allowed to come over, as well as my one roommate’s friend with benefits who doesn’t see anyone, even though that’s technically not allowed either.

Recently, my roommate just met someone new, and brought him over to our house without permission. I wasn’t home that night, so whatever. When I found out about it, I texted her saying that I’m not comfortable with her bringing anyone home except for the original FWB like we agreed. She was understanding.

However, the next day, she texted me asking if she could have the other guy over, too, since she is starting to really like him. I think it’s fair if all roommates are allowed one S/O over (in whatever form – boyfriend, FWB, etc) to fulfill our “needs” (if you will). So I respectfully told her that, and I said that if she wants to have the new guy over, she can no longer have FWB over because I don’t want to increase our risk of transmission. The more people we have in our house, the higher our risk. I told her that I wanted us all to be safe, and I am not comfortable having different guys over. I told her I am comfortable if she wants to see people outside, though.

Well, she kept pushing the issue, saying she doesn’t want to choose between them, and wants to make the “most of her last month” (since she is graduating this spring and moving away). I told her that I sympathize, but COVID cases are still on the rise, hence we need to be careful. Then she got aggressive and started completely criticizing my logic. Then she got our other roommate to advocate for her and tell me I’m completely wrong. I didn’t want the drama so I caved. I don’t think the new guy is very careful about the pandemic, since he hooked up with my roommate whom he’s just met.

I feel taken advantage of. I am upset because I am NOT comfortable having different guys over to our house because that directly exposes all of us to the virus. I would also like to point out that when cases spiked a few months ago, my roommates told me they weren’t comfortable with my boyfriend coming over, and I respected that. I did not see my boyfriend for 6 weeks. Don’t know what to do.
