I (33F) made grilled cheeses from HelloFresh about a week ago. They came with garlic butter. It had been hard to get the stuff to spread so I left it out on the counter thinking we might make another grilled cheese with it at some point. I had NO IDEA that a sealed, prepackaged garlic butter can’t be left on the counter like regular butter.

Fast forward to today when my boyfriend (33M) decided to make a grilled cheese. I said “oh are you using that butter?” He said yes. I thought it’d probably be fine and didn’t think much of it. I just shrugged it off and left for the gym.

He now has food poisoning and is furious with me for leaving the garlic butter out. He’s saying that this is entirely my fault and he should have known better than to trust me.

AITAH for leaving the garlic butter out? Is it my fault that he’s sick?

Edit to add: he’s kicked me out of our room and has said I’m not “taking accountability”. I want to take accountability if I’m truly at fault here. That is why I’m asking.
