So, recently, my boyfriend and I acquired a new rommate, who we will call B. He's known B for about 7 years now, so she isn't a stanger. However, B clings to him and truthfully, it's annoying. If I'm getting out of the shower - we have the Master bedroom with an adjacent bathroom and walk in closet - and naked, she won't realize that maybe it's time to leave the room. The other night this happened, and she was talking about, "Well if you get naked, I'll have to get naked, too." And it genuinely pissed me off, because I'm old school and another female naked around my man is, in my eyes, disrespectful. If we're in our room with our other roommate, she'll walk in uninvited to "see what's going on." She's pushing my buttons treating my room as a living room. ANOTHER instance was when my boyfriend walked to Whataburger, which is right next to their workplace, she came in and turned to him and demanded that if we left the workplace without her (We were still waiting on our other roommate to come get us all) we need to tell her, which also irritated me because I don't feel like we /have/ to tell her anything, and she certainly shouldn't be speaking so wild to him. I've been cheated on before, and I'm genuinely making an effort to not let my insecurities be the reason I don't like her, but holy shit does she genuinely piss me off.
