I live in a residence with a kitchen that is shared between 15 people. A girl who I know also lived here for two years, but this year she didn't during the first semester because of unrelated reasons. This week she just moved back in, after subletting the room to someone else for the first semester.

When she left in the summer, she also emptied out her closet in the kitchen. I put my stuff in this closet right after. Now yesterday when she came back, she moved my stuff to another closet, claiming that the one I had my stuff in was hers, because she used it last year. She didn't notify me that she was going to move my stuff.

I moved my stuff back, and when I notified her about it, she kinda freaked out. I'm shocked by the hostile nature of her messages, and absolute refusal to discuss it in person. She messaged me like I'm a stranger, not even considering for a moment the countless times I helped her out with things during the last two years. I temporarily moved my stuff to my room since there was no possibility to even argue, and I noticed the last few weeks that my things get used by other people, which I don't like. I'm ready to cut ties with this person and ignore her for the rest of the semester. AITA?
