How to handle roommates as an adult.

I’m curious since more and more people are opting to have roommates to keep living costs down. I’m one of them. I live in a 1500 sq foot 2bed apartment with my boyfriend, his best friend, and his bestfriend’s new girlfriend. It’s frustrating at times.

Those of you who hav had other roommates as adults, how do you manage when it comes to chores, splitting the bills, privacy issues, etc.?

I’m particularly struggling with the fact that I work from home, and my roommates seem to think I should pay significantly more of the rent because I use the space more. The other two knew before they move in, and said they were okay with it. Now they are telling be they are not okay with it, and I should compensate for their lack of privacy?! I’m currently paying 10% more rent, and think that is fair since I also cover ¾ of the electric bill.

What are your thoughts hints and tips? We are all in our mid- late 20’s and we each have steady full time jobs.
