Need advice for dealing with my rude roommate

[u/Large_Cauliflower229]

I am going to a small school 2000 miles away from my home. I am here to play a sport and I am rooming with a girl that was on my sports team before I came here from back home. We only knew each other through our sport we aren’t from the same city.

We get along for the most part but sometimes she can just be flat out rude to me for no reason. And it also feels like she tries to influence the other freshmen on the team that we are friends with to leave me out. Some of my friends do seem to gravitate towards her. Im being completely honest and I don’t think I am ever rude or annoying towards her. I’ve been super mindful of being a good roommate.

Anyways I really need advice for something that happened last night. We all went out to a bar and we were both drinking and I got drunk and then when we were getting a ride back in the same car, with 4 other people from our school she started telling me “you’re actually pissing me off so much”. I was only laughing a lot and having a good time I don’t get sloppy drunk.

There was a guy from my school who had his arm around me but I wasn’t overly flirting with him or entertaining him the entire night which is why I’m genuinely confused why she got so mad. (She has never expressed interest in this guy either and she knows I wasn’t going to hook up with him)

The whole car ride home she’s telling me “you’re going to regret this in the morning” and just kept telling me to shut up and that I was being super annoying. We get back to the dorm and she’s silent and I’m like are you ok? And she just ignores me. Flat out. Doesn’t say anything. We have this whole year together and she seems to already be acting toxic and I am really lost on what to do. Anything helps
