Alright, This won't be long because I got stuff left to do.

So I recently went to university abroad and ended up in a dorm corridor with a bunch of betas and and some girls. Most are antisocial and unattractive, but one of them is some obnoxious spoiled princess type of hoe. For some reason she's got a spot on the brain for me, talking around my back, throwing comments around, going through my shit, the whole nine yards.She knows I talk to and am seeing multiple girls and that I'm not the worshiping beta kind of guy, and I guess she has a problem with that. Anyway I usually deal with this mostly by ignoring or agree and amplify, but lately she is stepping up. She starts getting in conversations, talking over me and all that. And considering how beta my neighbors are, they usually just drop the conversation and engage in her prompts. Usually, I just carry on with my business or sometimes say that someone is being passive aggressive or something similar. I don't show it, but I have to admit it makes me angrier by the day as I know she is doing it on purpose. Where I come from, I'm used to just tell girls to shut the fuck up and this is what happens, but this is obviously not the case with these western brats.

So what advice do you have? What would you do differently?
