I’ve had this same experience, it was so terrible. I talked to her a lot of times, she’d stop for a while, then after few weeks, bring them back. I couldn’t study in at home. It got to a point I was always leaving the flat anytime it gets crowded. The day I stopped taking it from her was a night I was in my room, woh the music blaring from the speakers, then I heard my door opened forcefully. I was so scared, until I realized it was one of party guests. He was looking for the bathroom, then found himself in my room. It meant I wasn’t even safe in my own flat, a flat I co-owned. It was the following day I moved out of the flat. God some raise from my parents and I got me a new flat all to myself. Nothing beats living alone, you have the whole flat to yourself.
