So I live with 4 other people - 2 guys and 2 girls. One of the girls in particular constantly gives me shit. Like ultimate shit tests all the time. It's getting quite bad. And I'm honestly having a hard time keeping frame.

I wanted to go in the shower & she and her friend wouldn't let me in lol. They started quizzing me about this girl who I had over asking me if she was a ONS or girlfriend or something else. I wouldn't answer yet they kept on asking, she'd then saying stuff about my personality - how I don't give a fuck about anything. But she was saying in a negative way. They eventually get bored and leave the bathroom and join the party & let me shower. Sounds crazy typing this.

Later on I was just minding my own business drinking enjoying the atmosphere when she comes over, and starts shit testing to which I remain unreactive to. She says how "all of my existence is just annoying" in front of about 10 other people that we had over for drinks. Very embarrassing, rude & fucking disrespectful if you ask me. But I played it off as didn't want to sound butthurt in front of loads of my other friends.

How the fuck can I get her to stop saying such disrespectful stuff? Like it's bad when there's my reputation on the line. And, it's not a good environment to live in.

Tldr: Entitled rude bitch saying awful stuff as under disguise as shit tests and flirting. How to proceed?
