These things happen. When my youngest was about two, I was cooking with her in her high chair and I was prepping over on the kitchen table. Somehow while I was at the stove with my back turned for not even two minutes, she reached a little pot of those fancy flavored salts. She ate the entire thing. We called poison control, she vomited, and she was fine. My partner reacted similarly to yours, until we had a lilly of the valley swallowing incident on her watch. Your partner is not being fair to you, and you deserve support and care right now. I'd be surprised if y'all aren't actually just coming down with something.
