Bear with me, this is quite long. My roommate (20F) and I (22F) have been living together for close to two years. When I moved in, the house was seriously lacking in cleaning supplies as well as other things, for example the only thing in the fridge was a pot of melted chocolate and a spoon. My roommate has a large size dog, a Mastiff Ridgeback and Cane Corso mix who shed so there was dog hair everywhere. The day I moved in I went shopping and got essentials, things like cleaning supplies, dish soap and Laundry detergent Ect. After a few days it became pretty clear that she didn't own any of those things and was using mine. Fine, I didn't mind.

As time passed I started noticing that I was spending quite a bit of time doing more than my share of the household chores and cleaning up after her. I was spending upwards of Six hours a week washing dishes by hand, as we didn't have a dishwasher. I had talked to her about this and she said she would do better, and she did, for a week. I was also the only one buying things like toilet paper and paper towels.

Every time she had a party or her friends over to the house, I would spend the next day cleaning up the mess they left behind. I had tried leaving it to see if she would clean it as she claimed she would but two weeks would pass with no cleaning being done, so I would end up doing it anyways.

We have a spare bedroom that we use as a games/book room, I have my art supplies in there as well. My roommate had been throwing things into that room and just closing the door, to the point where it became unusable. I decided to get that room back into a usable state and spend a full day going through everything, throwing out garbage and sorting my stuff from her stuff, and getting it all organized. (i asked her to go through the small pile of things that i knew were hers, but didn't know what to do with and she didn't) I had gone away for a week to babysit for some friends of mine, while they went on a cruise and in the meantime my roommates sister had to move out of her place, and without telling me they put all her stuff into the spare room that I had just cleaned. And I don't mean put it in nicely, they shoved it in half-heartedly and closed the door. When I came home, ready to use the room I had just cleaned, I couldn't even get the door open because of all the stuff. I asked them to organize it a little better so we could get into that room and surprise surprise they didn't.

I talked to her multiple times, about making sure to keep the common areas of the house clean, like washing the dishes she uses or cleaning up her garbage from the living room (I no longer go in there as it's a disaster). She would clean up, for about a week before she stopped. I got advice from my friends and stopped cleaning up after her and washing her dishes to force her to wash them. I did, and she would use my dishes when she ran out of clean ones instead of washing her own, then would let them sit on the counter for about a month, growing moldy and disgusting before I couldn't stand the smell and washed them myself.

Here's where I might be the Asshole, I am moving out in a few weeks as I can't live here any longer due to a few other reasons, and am starting to pack up my things. The more I sort out my things from hers the more I realize she doesn't have any cleaning supplies at all. In the past two years she would just use mine, which again, I was fine with as she very rarely cleaned to begin with. I was cleaning the bathroom when I realized I bought the scrub brush and toilet plunger. Would I be the asshole if I took those with me when I moved out, leaving her to have to buy her own, on top of all the other things she also uses that I am taking?
