AITAH for “poisoning” my roommate after he kept stealing my food?

So, I’m a 25-year-old woman living with my roommate (27M). I used to live alone, but some financial struggles made me take in a roommate. A friend recommended him when I mentioned I was looking. Initially, he seemed fine—he doesn’t smoke or do drugs, so I let him move in. He splits the rent and utilities evenly, so it seemed like a good arrangement.

But recently, we’ve had major issues. I work late hours, so I always cook my meals in advance. For the first few months, everything was fine. Then, out of nowhere, I started noticing my food disappearing. I’d ask him about it, and he’d always deny it. Every. Single. Time. I tried labeling my food, but it didn’t make a difference—it kept vanishing, and it was infuriating.

Here’s an important detail: I’m not a big fan of nuts. I barely eat them, but my roommate is severely allergic. When he moved in, he told me about his allergy, so I made sure to avoid nuts altogether out of consideration.

But after weeks of my food going missing, I reached my breaking point. I live here, and it’s just the two of us. No one else comes over, so it had to be him. I even caught him eating my food a couple of times. At this point, it was just disrespectful.

One day, I made some ribs for myself, labeled the container, and even sent him a text with a picture, telling him not to touch it. When I got home, they were gone. Again. That’s when I decided enough was enough.

I went out and bought almond powder and mixed a little into a batch of mac and cheese—my trap meal. I made it clear it was mine and off-limits. I even sent another text with a photo, reminding him not to eat it. For good measure, I set up a camera in the kitchen.

Sure enough, when I got home, the mac and cheese was gone, and he’d left the container on the table. I knew he’d eaten it. I grabbed the camera and decided to head out to a bar instead of staying home. A few hours later, I got a call from his mom, who was furious. He’d ended up in the hospital with an allergic reaction.

She accused me of poisoning him. I calmly explained that it was my food, and I’d warned him not to eat it. I even sent her screenshots of the messages and the labeled container. She wasn’t having it, saying I was “careless” for having nuts in the house. I told her that I wasn’t responsible for his actions—he kept stealing my food despite being told not to. I also let her know I had video evidence.

She tried to guilt-trip me, asking if I cared about him at all. Honestly? No, I don’t. I’ve been patient for months, and he ignored all my boundaries. I’m not a monster—I didn’t put the nuts in his food; I just made my own food the way I wanted to.

Now, people are calling me a psycho. His family thinks I’m to blame, but I feel like I was justified. I’ve tried everything—talking, texting, labeling—and he still didn’t respect me. Sure, I feel a little guilty about the hospital bills because I know he’s broke, but at the same time, this was his own doing.

So, AITAH for trying to teach him a lesson?
