Frat roommate has gf over too much

First and foremost, I do plan on dropping the house for separate reasons, but this makes me want to leave sooner! Also, he has been spoken to twice both by myself and our housing manager.

So my roommate and I share a room in the house, we call these “day” rooms where you keep all your belongings, couch, tv, your desks as well. There is also a riser on one side where people often keep a bed setup. My roommate utilizes this room a bit too much, both for his own use and his girlfriend. We aren’t allowed to sleep in the day rooms, people still do it, my roommate included, but so does his girlfriend. Except it is every. Single. Night. Not only does it make things a bit awkward when I would like to change clothes, come in during the mornings to get ready (they sleep until 9:30 at the earliest, often past 11, I am in there around 8. ) They both smell badly, making a lasting impression in the room that doesn’t go away with candles or open windows. And they treat it as if she was the other roommate rather than myself. It really upsets me, especially when she’s there for hours during the day on top of spending the nights, and they leave a mess of the room which just fuels my despise. I’m kinda at a loss, and dropping right now isn’t ideal since we’re coming up on midterms and I’m not sure where I’d move for time being, but I really don’t like either of them and the lack of respect for my space, and belongings.

Sorry this is more of a rant, but any suggestions on my next move is greatly appreciated.
