Drama in Dorms

So, here's the thing. I'm not really one to get involved in the drama of college life, but this roommate situation is getting a bit too much for me to handle on my own. We've been roommates since freshman year and it's always had its ups and downs, but lately she’s been super clingy, constantly asking where I am or who I'm talking to. Last week, I found out she was going through my phone, reading texts from a friend that we both know doesn't exist (I made them up one day when I was feeling lonely). I confronted her about it, but now she's accusing me of being paranoid and overly secretive. Honestly, I just want the peace and quiet to study without constant questioning. Maybe I should've gone with my other roommate option back in August.
