AITA for cleaning my roommate’s room after asking her so many times and just deciding to do it myself?

Using a blank account since I don’t want anyone I know to see this. I (21F) recently got into an argument with my roommate (also 21F) over the cleanliness of our apartment. To start, I will say that I am a bit of a neat freak and like to keep our space clean. We rent a two bedroom two bath apartment, so we each get to have our own spaces. I take charge of cleaning our living room and kitchen because I told her that I have high standards and don’t expect her to change any habits to meet my needs.

Everything has been fine, but this past month I’ve noticed a foul odor coming from her room that’s starting to go into the rest of our apartment. It got so noticeable that my boyfriend said something about it last time he visited our apartment. I decided I had had enough and asked her about it earlier this week. She told me that she’s been really busy with work and classes (we’re college students) so she hasn’t had time to pick up, but if there’s a smell she’ll get to cleaning it. 

Well, a week had passed, and the smell still lingered. Unfortunately, it’s not a smell you can ignore either. It smells like rotten eggs and animal poop even though we don’t have any animals in the house? I talked to her again about it, and she gave me the same response that she’ll get to it later.

Now here’s where I might be the asshole, but I was just getting so tired of the smells that I decided to take matters into my own hands. My roommate was out for the day, so I peeked into her room to see where the smell could be coming from. What I saw was disgusting to say the least. Food and drink wrappers everywhere, unwashed laundry all over the floor, her room trashcan full of who knows what, and just overall a lot of junk. I’ll have to note here that my roommate is a little bit of a hoarder too, so she likes to hold onto stuff that I really don’t think she needs. Because she was taking so long to get rid of the smell, I decided to do a deep clean for her. I threw away all the trash she had in her room and all the food and junk. I threw out any clothes that looked like they couldn’t be washed and any stuff that she didn’t need. By the time I was done, it looked like a whole new room, and the smell was gone!

When my roommate got home, I told her that I had cleaned up her room. She was livid. She screamed at me for going into her room and messing with her things. She had been so busy with life recently, I just thought I was helping out. She’s stopped talking to me, and things are really awkward in the house. I do feel kind of bad, but I was just helping out. How can I convince her that I did the right thing?
