To put it in perspective, I have obsessive compulsive disorder (OCD) and one of my worst fixations is my bedroom/bed, and keeping it clean and exactly how I need it to be. I say this so you know that my bedroom is too a safe space for myself and I feel very strongly about it!

I would still allow your dad to sleep in my bed in this situation lmfao. It’s just common human decency, and it’s truly not that hard to just throw on disposable sheets if she wants or get a $50 mattress topper. It might make my eye twitch a little, but there’s no reason to treat family so poorly TBH. It’s insanely shitty and you should definitely insist.

I mean, or you can just set up the air mattress for your dad and everything and then just tell him to sleep in the bed anyway. She would literally NEVER know. But that’s bad advice.
