I'm thinking that my boyfriend and I shouldn't pay more rent, because we share the same room.
Why not? What does it matter if you share the same room?
I just think we have the perfect relationship since we live in the same room and so shouldn't have to pay more rent.
Just because you both share the same bedroom, doesn't mean that you should have to pay less rent. You need to pay what you owe or else you may be kicked out of the apartment.
Why does everything have to be so complicated?
Because that's the way the world works.  People don't just allow others to live where ever they want without having to pay anything.
