Hey everyone, I'll get straight to the point. Normally, I like to entertain people at my place, but my roommate brought people over during the stay-at-home orders (this is in NY). I asked him to have them leave because I wasn't about to risk another 3k emergency room bill because of my roommate's stupidity. They eventually left and I thought I had made things clear.

Apparently not. he's brought someone over again tonight for the 2nd time in a month. What are alternate methods of confrontation since talking it out doesn't work? My knee-jerk reaction is to physically fight, but that won't do anyone any good.

Some background: grew up with no male figure in my life, etc etc. So I'm really behind on how to deal with confrontations with other dudes.
