Separate rooms?

Does anyone have a separate room from your partner? If so, why/how? I want my own room but hubby is not on board. My reasons may seem artificial but my husband can be a slob. I feel like a servant constantly cleaning after him, the bathroom alone is gross and im just sick of it. I rather have my own space I can maintain the way I want. I have 3 kids 12, 2, 7mo. Im always cleaning, it annoys me I have to clean after him more than them combined. The room always stinks bc he puts diapers in the room trash and never takes it out instead of putting it in the diaper pale. He also puts food trash in the room trash instead of kitchen. I don't want bugs in out house so I've asked him 10000000xs to not put food in the bathroom trash but he continues. He cuts his hair and leaves it. Shaves and leaves his cream stuff in the sink without rinsing it so it sticks, same with toothpastes. Stuff I'm sure other men might and some may not be a big deal but for me it is. Theres more but it's already a long post. I get anxiety when there's mess and disorder. And frustrated when I have been repeating things for yrs. Also before we got married I always slept with tv on bc I can never sleep just laying there. I have to be doing something, even if I'm tired I need something to put me to sleep. Hes the type that can sleep at the drop of a hat but when we got married he said he can't sleep with TV on so I had to suffer with no tv. I turned to my phone, play games, scroll fb etc but he says it's inappropriate to be on my phone late at night. So he expects me to stare at the ceiling and listen to him snore. My 7mo old still wakes up all through the night so I never go into a deep sleep anyway and I'm always feeling anxious to tiptoe and hurry to hush the baby and not wake him. Also he complains that I go to sleep too late bc I wait until night time to clean my house b4 I go to bed after my toddler makes a mess all day, when I put him to bed, I do all my cleaning and making my baby's milks and such, it takes time. He claims it takes too long and I need to start earlier so I can get to bed earlier, when he does. He complains I take too long and will just keep coming to ask me how much longer instead of offering to help me get done faster. I tell him to go to just go to bed and leave me be but he says he can't sleep without me which is why he's rushing me. We were separated for a few months, same house different rooms, and I got comfy working at my own pace with no extra stress and doing what I needed to do, how and when I needed to do it. And having a clean space. Now back in the same room and I feel trapped again.... before I moved back in the room with him thing were much better for me, spend time together but at night we just go to our own rooms. If he has needs we still take care of that but go to our separate rooms after. It may sound selfish to say things were better for me but before, things were good for him and not me. Everything was his way. So it's hard to figure out where the compromise is?
