am i overreacting cuz

I FINALLY decided to stop showering at my apartment because my friend and roommate never cleans up after herself in there. The tub is full of hair, her snot and what seems like dead skin flakes everywhere. You can't turn on the water without it pooling up immediately at your feet and all that nasty getting on you. I've been tolerating it because I thought she would have the decency to not make such a disgusting mess and like an idiot, gaslight myself "oh why not just clean a little bit, it's no big deal" but I'm moving out in like 3 months anyway so I guess I'll start my move early and cease cleaning any mess that I didn't personally make. My family home is 5 minutes away so I'm just gonna do the travel and shower there.

I am excited to see how dirty it gets until she finally decides to clean it. Cuz it ain't my problem anymore I'm showering somewhere else.

And yes, I've already made it clear in the beginning she needs to clean up after herself BUT SHE JUST KEEPS DOING IT ANYWAY so dont need to tell me to communicate with her. It's a lost cause. With the messes she leaves, it is CLEAR no one needs to tell her to clean, she just chooses not to.
