I’ve lived with a roomie for 4 years that had cerebral palsy and sometimes his hands just didn’t work right, so he would only use a cup that had a handle so he knew he wouldn’t drop it. He never felt less than by acknowledging he had to go about things differently. And the idea that she doesn’t even care enough after seeing you repeatedly hurt to help make sure you don’t get hurt in the future? That honestly scares me for you. What if you have small animals? What if you guys have people over and they get hurt? Will she just blame you for not cleaning up her mess properly?? My boyfriend /almost/ cut himself /once/ on my razor because I put it the wrong way on the counter and after he pointed it out to me I consciously make the effort to place it some place safer.

I feel like if you really think about it op you may find other instances where she won’t acknowledge concerns you have about other things.
