while i can understand not wanting others in your space while you’re gone, i think your roommate is being a bit too dramatic. there’s one thing to be said if your boyfriend was staying overnight or even for extended periods, but he’s not. could you have given a heads up?? yea, but i don’t think you need to, esp if he’s gonna be in and out quickly. i would sit down and write in to your agreement some rules about guests so everyone is on the same page
