<human>: Can you summarize the given text in a few sentences?

My bf's best friend moved into one of our spare bedrooms to help us with rent a month ago. Things went to shit starting day one. I came home from work and he had put all his extra furniture including his cat litter box in our living room and dining room, making it a cluttered mess. Note: we have two living room areas and his furniture set occupies the other one.

Now I am very allergic to cats but I comprised by letting him bring it because we needed the extra rent money. So he lets his cat all over ny furniture knowing this and won't remove him from them, waits until his cat box is overflowing with shit to empty it and my whole house smells terrible now. I get to enjoy the nice smell of cat shit in my dining room every morning at breakfast. But the worst part about him not taking care of his cat is that he claws up my brand new couch that I just paid off 3 months ago. It is the first nice thing I have ever bought myself in my adult life and I purchased an expensive set.

I work a minimum wage job part time and saved for years to finally have nice things. He on the other hand throws money around and only eats out at restaurants.

I never received an apology for the couch and his cat continues to claw it up. If I mention anything about it to my bf I am met with "Well that couch isn't that nice anyways". No use talking to the best friend because he is a lazy piece of shit that won't sweep up the cat litter from all over the floor. It gets tracked up to my bedroom which is past the two living rooms, upstairs and far down the hall from the box! I am the only one who vacuums, sweeps, mops, dusts his cats fur and vacuums the fur off my couch.

I am just fuming and almost always in tears because this situation is driving me crazy. And how does everyone react? I am being over emotional and complain too much.

I wish moving out was an option.
