MIL uses the laundry to control me and make me look like I don’t do anything

We live in MIL’s house temporarily and I’m starting to realize she’s using the laundry as a way to control me and make me look like I’m lazy or unproductive. When we first moved in, she told me I couldn’t do laundry on weekends because that’s when she needs it. Fine. I figured that meant I’d have access during the week.

Nope.

If she’s home during the week and hears me using the machines, she comes rushing downstairs like she’s trying to catch me in the act, then suddenly decides she needs to do laundry too. Even though she didn’t actually do it over the weekend like she said she would. She and her daughter might do one or two loads across the whole weekend and then leave it sitting for hours. I know because I live in the basement where the machines are. I see who’s coming down and when. She’ll say her daughter is supposed to switch it, but then her daughter just… doesn’t. And it sits. And I’m still the one not allowed to use it.

Now that it’s hot outside, she’s started using the excuse that the dryer makes the upstairs too hot for her other adult son’s room. That man is never home. He’s always at his girlfriend’s. And the house is central air. It’s literally freezing inside all day. She just keeps pulling excuses out of thin air to block me.

Meanwhile, my laundry is piling up in our small living space. She knows there’s nowhere for it to go. She sees it. And I swear she does it on purpose to make me look like I don’t do anything. I hate clutter. She knows it stresses me out. It feels intentional, like she wants me to look incompetent while also making me miserable.

I brought it up to my husband and he said, “I’ll just tell her I need to do laundry because I don’t have clothes for work.” I told him, do you realize how messed up that is? That it has to come from you, and only works because it’s for your job? What about me and our two toddlers? We need clean clothes too.

And it’s not just once in a while. Every time her daughter stays home from school and MIL isn’t here, which is honestly a lot, MIL will call or text her and tell her to go do laundry. That’s a story for another time, but the kid fakes sick constantly and has behavior issues. It’s the same pattern. That’s the time I’m supposed to have access, when MIL is gone. But she makes sure someone else claims it before I can.

It’s like a game of keep-away, but with basic needs. And I’m so tired. I’m stuck sitting in the mess that she won’t let me clean up, and then she gets to point at the mess and act like it’s my fault. I feel like I’m being set up to fail.

Has anyone else dealt with this kind of weaponized “house rule” nonsense? I feel like I’m losing my mind. Please tell me I’m not the only one.
