Input: TL;DR: Moved in with a roommate who eats my stuff and is messy. I left her a note about it and she left me one calling me "rude and disrespectful".

I am 20F and recently moved into my first apartment. I have definitely carried over some of the expectations I had about living with family members, and don't know if I have gone too far. 

My roommate Maggie and I were strangers before she moved in. I allowed her to use my dishes, appliances (fridge, stove, washer, dryer), pots and pans freely. Almost immediately she began eating my food and letting dishes pile up. She would also get up in the middle of the night to eat and would make a lot of noise. I called her out at once for all these things. She mostly ate only the staples I had, but I noticed she used my ketchup, oil, pasta, salt, pepper and popcorn. Not a big deal but I asked if in the future she would at least ask me before using my things. She agreed to this, but never ended up asking me.

As the weeks went by, she continued not pulling her weight around the house and I called her out many times, sometimes a bit rudely, about the following things: 

\- Eating my food

\- Not doing her dishes

\- Smoking pot inside (we had both signed a waiver saying we wouldn't smoke inside)

\- Removing the plastic from her window (results in high electricity costs)

\- Paying rent and utilities over a week late

\- Pooping in our only toilet and not cleaning it up once when we were out of water

\- Leaving trash bags outside on days it wouldn't be picked up (we could be fined $300 for that)

She always apologized and said she would stop, (although she lied to me and said she didn't smoke. I can smell the pot from every room in the house).

Recently she changed her phone number and didn't give me the new one. She didn't like me knocking on her door (she's in there 24/7). So a couple days ago I left her a note. I asked how she was doing and if she wouldn't mind wiping down the stove when she was done because she left it oily. I mentioned a few other house-keeping related things and asked for her new number. I have confirmed with friends that my note isn't hostile whatsoever. When she found it, she crumpled it up and wrote me one where she said she would rather not give me her phone number, because quote "You're rude and disrespectful. You have the mood pattern of an autistic child who needs a fucking nap. I'm sick of your shit and I don't need you blowing up my phone with dumb bullshit, disrespect and negativity." I am shocked because the few times I have talked to her face to face we have been nice to each other. After leaving her note out, she went and ate more of my popcorn. I have been living with my boyfriend ever since and am scared to return. But is she the right one in this case? Did I push things too far by constantly nagging her?
